Aseptic vial filling is one of the most unforgiving processes in pharmaceutical manufacturing. A single deviation in containment, dosing accuracy, or operator handling can contaminate an entire batch, trigger a regulatory hold, or write off a high-value biologic formulation overnight.

For Plant Managers and Procurement Heads, the real question is not whether aseptic filling is challenging. It always is. The real question is whether your current aseptic vial filling machine actively reduces risk or quietly increases it through manual handling, inconsistent dosing, and unplanned downtime. HMPL SteriShield is purpose-built to eliminate these challenges by delivering precise, reliable, and compliant aseptic vial filling performance.

Before looking at any solution, it helps to name the problem in numbers your finance team already tracks:

Product wastage: Every percentage point of fill-volume variance on a high-value biologic or oncology drug translates directly into lost product cost.
Unplanned downtime: Manual nest handling and changeovers between batches add non-productive hours that procurement rarely budgets for upfront.
Compliance exposure:A contamination event during fill-finish can lead to batch rejection, regulatory deviations, and significant production losses.
Operator safety risk: Open or semi-open filling environments increase operator exposure when working with cytotoxic or high-potency formulations.

SteriShield is engineered as a fully integrated aseptic filling line rather than a collection of standalone stations, making it ideal for 0.2 ml to 5 ml vial applications. Every stage, from nest handling and precision filling to stoppering, capping, and final rejection, operates within a single controlled and validated environment to ensure product integrity, process consistency, and regulatory compliance.

1. Isolator or Closed RABS Containment

Manufacturers can specify either a full isolator or a Closed Restricted Access Barrier System (RABS), depending on the potency profile of their product and existing facility design. Both configurations maintain Grade A conditions around the filling zone while protecting operators from exposure.

2. Servo-Driven D-Nesting and XY Gantry Vial Placement

Pre-sterilized nested vials are automatically de-nested and transferred using a high-precision servo-controlled XY gantry system. This advanced automation ensures accurate, repeatable vial positioning throughout the process, enabling high-speed handling of small-format vials while minimizing human intervention and maintaining aseptic integrity.

3. Precision Piston Pump Filling with Volumetric Accuracy up to 0.2 ml

As global supply chains become more demanding, reliance on outdated, manual, or semi-automated packaging processes is no longer a viable business strategy. This comprehensive guide explores the deep engineering principles behind advanced liquid filling systems, details the critical components of complete turnkey packaging lines, and examines how industries ranging from food and beverage to pharmaceuticals are leveraging an advanced automatic liquid filling machine to achieve unprecedented throughput and regulatory mastery.

Understanding Fluid Dynamics for an Automatic Liquid Filling Machine

The most fundamental engineering challenge in liquid packaging is managing the unique physical characteristics of the product being dispensed. Liquids behave radically differently under pressure, temperature variations, and kinetic movement. Applying a generalized, one-size-fits-all approach to filling machinery inevitably leads to catastrophic product waste, inconsistent dosing, and severe mechanical downtime.

The Critical Role of Viscosity in Pump Selection

Viscosity—the scientific measure of a fluid's resistance to flow—is the primary defining metric that must dictate the selection of your automatic liquid filling machine's pump and nozzle architecture. Free-flowing liquids, possessing a water-like viscosity, behave predictably but require careful handling to prevent splashing and product aeration. For these applications, engineers typically deploy standard volumetric systems utilizing highly sanitary peristaltic pumps. Peristaltic pumps ensure absolute sterility, as the liquid only makes contact with the internal flexible tubing, entirely bypassing the mechanical components of the pump itself.

Conversely, semi-viscous to highly viscous liquids present entirely different flow dynamics. Products such as heavy edible oils, cosmetic creams, honey, and petroleum jelly flow sluggishly and require immense mechanical assistance to move from the hopper to the container. For these challenging formulations, manufacturers must deploy piston filling machines or highly pressurized, servo-driven automatic liquid filling machine setups. Piston pumps provide the necessary pneumatic or mechanical force required to handle high-viscosity liquids, precisely pushing the heavy product out through the filling nozzle and severing the liquid stream cleanly to prevent dripping.

Engineering Metric Insight: For high-value formulations, precise pump synchronization via advanced PLC controllers minimizes unrecoverable financial losses due to product overfill across millions of production runs.

Engineering Solutions for Foaming and Suspended Particulates

Certain liquid formulations, particularly heavy-duty detergents, dairy products, and specialized chemical solutions, are inherently prone to severe foaming when agitated or dispensed at high velocities. To combat this phenomenon, advanced volumetric systems utilize a highly synchronized diving nozzle system.

Diving nozzle system preventing liquid foaming during bottle filling

Figure 2: Precision Material-Specific Solutions for Eliminating Aeration and Turbulence via Specialized Diving Nozzles.

In this mechanical configuration, the filling nozzles descend deeply into the container before the dispensing cycle initiates. As the liquid level gradually rises, the nozzle slowly retracts in perfect synchronization, ensuring the dispensing tip remains submerged below the surface of the liquid throughout the entire fill cycle. This sub-surface filling technique entirely eliminates the aeration that causes foaming, allowing for maximum operational speeds without the risk of product overflow.

Furthermore, liquids containing suspended particulates—such as pulpy citrus juices in the beverage industry or suspended active solids in certain agrochemical slurries—require specialized engineering. The internal pathways, valves, and pump chambers of the automatic liquid filling machine must be adequately sized and contoured to allow particulates to flow unhindered. This careful sizing prevents the clogging of nozzles and ensures a uniform, homogenous distribution of the solid particulates within every single container processed on the line.

Core Technologies: Categorization of Liquid Filling Machines

The selection of appropriate filling machinery is intrinsically linked to the facility's required bottles per minute (BPM), the desired level of labor automation, the available footprint, and the specific industry application.

Automatic Volumetric Liquid Filling Machines

Automatic volumetric fillers serve as the primary workhorses of the global packaging industry. State-of-the-art systems, such as the Automatic Volumetric Liquid Filling Machine engineered for 15mm to 90mm diameter glass and PET bottles, operate utilizing hyper-precise syringes and adjustable dosing blocks. The hallmarks of elite automatic liquid filling machine systems include several critical engineering features:

High Precision Tolerances: Advanced machines guarantee a ± 1% filling accuracy tolerance on a single dose. This precision is critical for expensive pharmaceutical or chemical formulations where a 2% overfill across a million units results in massive financial losses.
Intelligent "No Bottle, No Filling" Mechanisms: Integrated smart sensors continuously monitor the presence of a container on the conveyor belt. If a spatial gap is detected, the machine's PLC instantly halts the specific nozzle operation for that position, preventing product waste.
GMP-Compliant MOC Standards: To comply with strict Good Manufacturing Practice (GMP) requirements, the heavy-duty frame structures feature MS painted cladding with access doors constructed of SS 304. Crucially, every single component that makes direct contact with the liquid product must be manufactured from premium SS 316 stainless steel to prevent corrosion, pitting, and ensure absolute sanitation.

Machine Configuration	Throughput Range (BPM)	Material Compliance	Optimal Fluid Types
2-Head Entry System	10 - 20 BPM	SS 304 / SS 316 Contact Parts	Free-flowing Liquids, Low Viscosity Syrups
4-Head / 6-Head Modular	30 - 60 BPM	SS 316 Premium Contact Parts	Semi-viscous Oils, Standard Chemicals
12-Head Servo-Driven	100 - 120 BPM	Full GMP SS 316L Framework	Highly Viscous Creams, Foaming Detergents

These automatic systems are highly modular and scalable, available in diverse configurations ranging from entry-level 2-head systems scaling up to massive 12-head servo-driven systems capable of sustaining 100 to 120 Bottles Per Minute during continuous 24/7 operations.

Semi-Automatic Piston Filling Machines

While a fully automatic liquid filling machine dominates high-volume manufacturing, semi-automatic piston filling machines offer immense strategic value for smaller operations, pilot plants, and facilities handling extremely viscous materials in smaller, diverse batches. The primary advantage of semi-automatic machinery is extraordinary flexibility. They require lower initial capital investment, feature significantly shorter changeover times due to their simpler mechanics, and allow facilities to rapidly pivot production between vastly different product formats and viscosities with minimal engineering intervention.

Architectural Integration: Designing Turnkey Packaging Lines

A high-speed filling machine, regardless of its precision, cannot operate efficiently in an isolated vacuum. To realize true industrial ROI, manufacturers must implement complete turnkey packaging lines where every upstream and downstream process is seamlessly automated, synchronized, and monitored.

Phase 1: Precision Washing and Absolute Sterilization

Before the automatic liquid filling machine process can commence, containers must be impeccably clean. Automatic rotary bottle washing machines utilize sequential, high-pressure jets of water, compressed air, and specialized chemical cleaning agents to remove dust and microscopic particulates. In the highly regulated pharmaceutical sector, this washing phase is immediately followed by passage through advanced Sterilization Tunnels. These massive thermal units subject glass vials or ampoules to extreme dry heat, ensuring absolute sterility and the destruction of all pyrogens before the containers are allowed to enter the highly classified cleanroom filling environment.

Figure 3: Sterile Tunnel Integration for Cleanroom Upstream Container Processing.

Phase 2: Hermetic Sealing and Capping Machinery

Once the precise volume of liquid is dispensed, the container must be immediately and securely sealed to maintain product integrity, prevent oxidation, and secure it against contamination. Continuous thread cappers use sets of matched, precisely calibrated discs to spin caps down onto bottles as they move rapidly along a conveyor system. Vibratory bowls or mechanized elevators act as auxiliary equipment, automatically feeding the caps into the sorting chute to ensure a continuous supply. For comprehensive system setups, advanced Sealing and Capping Machinery ensures hermetic integrity across vast production batches.

For the distillery and pharmaceutical industries, Roll-On Pilfer-Proof (ROPP) capping machines are the standard. A specialized, rapidly rotating capping head descends, and precision rollers form the threads directly onto the bottle while simultaneously tucking a tamper-evident ring under the neck finish, providing both a hermetic seal and undeniable tamper evidence.

Phase 3: Traceable Labeling and End-of-Line Packaging

The final stages of the turnkey line involve high-speed automatic sticker labeling machines. These versatile units can apply wrap-around labels on round bottles, or execute precise double-sided label applications on flat containers, at speeds that perfectly match the upstream equipment. For advanced compliance, particularly in pharmaceuticals, these labeling machines are inextricably integrated with 21 CFR Part 11 compliant computer systems, ensuring rigorous digital traceability and immutable audit trails.

Following the labeling phase, shrink sleeve applicator machines apply full-body graphical sleeves or tamper-evident neck bands. The containers then pass through specialized shrink tunnels, utilizing controlled heat to conform the plastic seamlessly. Finally, automated case packers and highly accurate multihead weighers prepare the individual units for palletizing, ensuring the final shipped product meets all weight regulations prior to global distribution.

Sector-Specific Compliance and Application Engineering

Advanced Pharmaceutical Packaging Lines

The pharmaceutical industry operates under the most stringent, unforgiving regulatory environments globally. Injectable medications, which bypass the human digestive system and enter the bloodstream directly, require packaging architectures that guarantee absolute sterility, stability, and impenetrable Container Closure Integrity (CCI). Highly sophisticated Pharmaceutical Packaging Lines managing vials—whether utilizing moulded glass for structural mechanical stability or tubular borosilicate glass for high precision and thermal resistance—must be handled with extreme care to prevent micro-fractures during high-speed transit from the automatic liquid filling machine.

Furthermore, Water for Injection (WFI) containers represent the absolute pinnacle of sterile packaging requirements. They must be manufactured with high-grade, infinitely secure seals to maintain absolute purity, preventing any microscopic ingress of environmental contaminants that could catastrophically compromise life-saving medical formulations. The industry is also seeing a massive shift toward advanced robotic pre-filled syringe (PFS) filling and stoppering machines.

Chemical and Agrochemical (Pesticide) Operations

The packaging of industrial pesticides, concentrated fertilizers, and raw chemicals presents unique, life-critical hazards. These liquid formulations are frequently highly toxic, intensely corrosive, and volatile. The entire packaging line in these facilities must be constructed with specialized anti-corrosive materials. Filling accuracy is paramount, not merely for corporate cost control, but to strictly comply with severe environmental and safety regulations regarding the transport of hazardous materials. Automatic induction cap sealing machines are heavily utilized in this sector to fuse a foil seal across the bottle opening, providing a hermetic barrier that prevents dangerous leaks during transit.

Distillery and Premium Beverage Processing

In the global distillery sector, packaging operations must preserve the precise, delicate chemical composition of high-value alcoholic beverages—like premium whisky, aged rum, and distilled vodka—while simultaneously maximizing consumer shelf appeal through flawless presentation. Filling machines in distilleries must handle high-proof, highly flammable alcohol safely. This often necessitates the engineering of explosion-proof electrical enclosures and entirely pneumatic control systems to eliminate ignition risks. Furthermore, the equipment must handle premium glass bottles delicately to prevent any visual scratching or scuffing, and apply highly secure closures—like natural cork stoppers or ROPP aluminum caps—to prevent oxidation and the disastrous evaporation of volatile aromatic flavor compounds.

Technical Frequently Asked Questions (FAQs)

Q: How does the specific viscosity of a liquid impact the selection of a filling machine pump?

A: Viscosity is the absolute critical determining factor in pump architecture. Water-like, free-flowing liquids are best handled by gravity fillers or peristaltic pumps. Conversely, highly viscous liquids like heavy industrial oils, cosmetic creams, or honey require the immense mechanical force generated by piston pumps on an automatic liquid filling machine to ensure accurate dosing.

Q: What is the strategic difference in ROI between semi-automatic and fully automatic packaging machinery?

A: Semi-automatic machines are ideal for operations featuring smaller batch sizes and requiring frequent format changeovers due to their high flexibility. However, for facilities aiming to scale exponentially, investing in a fully automatic line provides vastly superior long-term ROI. This is achieved through massive labor reduction, minimized product giveaway via strict ± 1% accuracy tolerances, and consistent, uninterrupted 24/7 throughput.

Q: How do advanced volumetric filling machines physically prevent liquid foaming and spillage on the line?

A: Elite volumetric machines utilize a synchronized diving nozzle system. The metallic nozzles mechanically descend to the very bottom of the empty container and slowly rise in perfect tandem with the dispensing liquid level. This ensures the dispensing point remains constantly submerged, preventing the aeration that causes severe foaming.

Q: Why are SS 316 and SS 304 materials legally mandated in pharmaceutical and food packaging machinery?

A: Stainless Steel (SS) 304 is typically utilized for the machine's external frame cladding due to its excellent structural durability. However, Stainless Steel (SS) 316 is strictly mandated for all internal wetted parts that make direct physical contact with the liquid product (such as the syringes and nozzles). SS 316 contains the element molybdenum, which provides vastly superior molecular resistance to corrosion, pitting, and chemical degradation.

Optimizing Production with Turnkey Packaging Solutions

The strategic transition from outdated manual or disjointed processes to fully integrated, turnkey packaging lines represents one of the most significant operational upgrades a manufacturing facility can execute. By deeply understanding the specific rheological requirements of a product's viscosity and the exact tolerances legally required by industry regulations, industrial manufacturers can drastically reduce waste, guarantee compliance, and maximize long-term throughput.

When evaluating capital equipment investments, partnering with a machinery manufacturer that understands the complex nuances of complete line integration—spanning from sterile washing and an advanced automatic liquid filling machine to high-speed digital labeling and automated case packing—is not just an operational choice; it is a foundational requirement for long-term industrial dominance.

When you work in a business that uses liquid-filling machinery to package products, you know that having the process be as automated as possible is the goal. For instance, having volumetric fillers help fill liquids into containers at an even, consistent fill level, while cooling conveyers help molten products cool off more quickly than traditional conveyor belts. One of the last steps in automating the process for a lot of businesses is the capping or sealing of the product. Many businesses choose to do at least part of this process manually, from filling the hopper of caps to the actual capping of the containers. Not only is this a tedious process, it takes a lot of time that can be spent focusing on other aspects of your business. Thankfully, several different machines can help mitigate the difficulties that come along with manual capping.

Cap Elevators

Cap elevators allow caps to be stored until they’re ready to be used. Rather than keeping the caps in a box somewhere, this automatic elevator hopper is designed to supply caps to an automatic capping machine down the line. The machine is activated when the hopper to a capping machine is getting low. It is designed to feed a wide range of different-sized caps, from 10mm to 110mm, so is a versatile choice when you want to automate the first part of the capping process—the actual act of finding the caps.

Cap Sorters

Cap sorters are a helpful machine that helps position caps so they are facing the correct direction when the capping machine picks them up to be used. Cap sorters are available in an elevator setup, which helps bring up a supply of caps to the capping machine, or a vibratory setup, which works by shaking the surface that the caps are on until the cap switches to being positioned correctly. These machines ensure that the capping machines can do their job efficiently once the caps are ready to be placed.

Capping Machines

Finally, the capping machines themselves are what place the caps onto each container. For these types of machines, there are four options – spindle cappers, chuck cappers, snap cappers and wheel pluggers. Spindle cappers spin the lids onto the product as the container sits stationary underneath a station. Chuck cappers also spin caps onto containers, but this machine is designed to keep the products moving at a consistent pace, so the lid is placed on the container and then the container runs through the machine, which has lid tighteners along the top. Snap cappers snap the caps onto the container tightly, and vertical wheel pluggers are used for containers that require plugs rather than lids or caps.

Saving time is easy when you use capping machines from HMPL. Don’t stress yourself out by continuing to manually cap your products. Instead, use these machines to automate the process, and you’ll be surprised at how much more you can get done!

When your business packages liquid goods, applying a cap or lid to each container securely is an essential part of the process. If you’re not currently shipping out a lot of products, or if you don’t have a complete packaging line up and running quite yet, you may not have implemented having a capping machine into the line yet. If you’re still capping your containers manually, you could be wasting a lot of time making sure that each cap is tightened or snapped securely into place. Instead, consider automating the process by integrating an Automatic Cap Sealing machine into your line.

Why Use Capping Machines?

Automatic Capping Machines not only speed up the process of finishing the packaging of your product, but they also ensure that each cap is sanitary and that the product does not get contaminated by handling. Additionally, they allow you to save yourself from the repetitive motions of placing and tightening caps to each container yourself. There are several different capping machines that can help you pack more product in less time—and not just the machines that place the caps on, either.

How Can Capping Machines Benefit Your Business?

Capping machines can not only save time, but they can streamline the process of placing caps on containers and getting products ready for shipping. For example, instead of having to manually sort caps or manually place and tighten caps, you can let a machine do all the work for a uniform, consistent result. If your containers require plugs and not proper caps, some machines can take care of that job, such as automatic vertical wheel pluggers. Save time and produce more consistent packaging with automated machinery. Add in a piece at a time, or purchase an entire system at once—whatever your budget allows.

Types of Capping Machines

Among capping machinery, there are a few different classes – the actual capping machines, cap sorters and cap elevators. Cap sorters work with the caps to orient them correctly before sending them along the line to the capping machines for placement. Cap elevators are part of a cap feeding system, and they are used to increase the efficiency of automatic capping machines as well as container unscrambling as the caps are pulled from a hopper and then transported to the next stop in the line. As for the actual capping machines, those include:

Chuck cappers: Chuck cappers work by placing a cap onto a container, and then sending it through the machine, where the moving parts spin the cap so it is sealed tightly. With this machine, the container is in continuous motion, rather than stopping at a spin station, as happens with spindle cappers

Spindle cappers: A similar machine to chuck cappers, instead these stop the containers at stations and spin the caps onto the container while the containers remain stationary.

Snap cappers: Snap cappers work by pressing a snap-on cap to each container as it traverses through the machine.

Vertical wheel pluggers: Finally, wheel pluggers are used where the containers being sealed require a plug instead of a cap placed on top.

What Industries Use Capping Machines?

Like most packaging machinery, capping machines are used in a variety of different industries. Just a few of these industries are:

Beverage and food
Distilled spirits and wine
Candles, lip balms, and molten products
Cleaning products
Pharmaceutical and medical
Paints, stains, and sealants (home improvement)
Personal care/health and beauty

When you are looking to buy a machine that can be used for capping bottles, you should definitely consider getting a ROPP capping machine or a roll on pilfer proof closure machine. These packing machines have been introduced many years ago but over the years they have improved in their technology and efficiency which ensures better performance each and every time. Basically these machines include a robust unthreaded aluminum shell which is placed over the neck of the bottle. As the machine presses down, it has numerous thread-forming wheels spin right around the shell to press against it. This helps to conform to existing threads of a bottle and the locking ring.

A ROPP capper is very similar to a chuck capper even though these machines do not involve any clutch mechanism. The ROPP capping machines can be purchased as single head systems or multiple head systems that come with high speed rotary features. A major advantage of ROPP capper machine is that it seals a product and delivers tamper evident security at the same time. However, a downside of using a ROPP capper is that it’s generally expensive to manage more than a single cap size. The threads and neck of the bottle has to be hard enough for withstanding the pressure needed to form the threads. For this reason, these machines are mostly used with hard plastic or glass.

The latest ROPP capping machines are designed and manufactured by using superior quality stainless steel materials and they also come with hard chrome plating and SS cladding to confirm complete resistance to corrosion and improved longevity. They also come equipped with single motor synchronized conveyor, platform turret and star wheel. The good thing about these machines is that they also feature self-lubricating properties which helps in reducing friction in a big way. The noiseless and smooth conveying of the capping process also makes them a hot favorite among various companies. Since they always deliver vibration free operation for all kinds of projects, they are always deemed useful for different types of projects. Additional features that come with these machines include an adjustable torque as well as low power consumptions with a low noise level. Many of the ROPP capping machines that are available these days include an acrylic cabinet, motorized height adjustment feature; a safety guard for protection and operation as well as specially designed hopper for increasing the storage capacity of the bowl.

The good thing is that there are multiple models of automatic and semi automatic machines these days that can be used for advanced bottle capping requirements. The productivity level associated with these machines varies greatly on the model that you opt for needs. This means that when you choose to buy these products for your business, you can expect your company to effectively deal with the market competition. Therefore, once you have decided to buy these machines, make sure that you consult a reputable manufacturer that can provide you with state of the art ROPP capping machines.

There are different cap types and sizes which seem unlimited, but the number of available capping machines is surprisingly low to cover all types of caps. Of course, unique container tops may require customized capping machinery. For almost all other caps, a small group of capping machines will “seal” the deal.

Types of Capping Machine

Spindle Capper Machine

Spindle Capping machines are probably the most popular capping machine produced for the packaging industry. These cappers use sets of matched discs to spin caps down onto bottles or other containers as they pass through the capping area on a conveyor system. Normally, three or four sets of discs will be used to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to each bottle, leaving the operator of the machine to simply replace bulk caps as needed. These capping machines can handle a wide range of screw-type caps, including flat caps, sports caps, trigger sprayers, and many more. The flexibility and ease of operation are two factors that make this capping machine popular.

Chuck Capper Machine

Chuck capping machines are similar to spindle cappers in that they work with screw caps. Chuck cappers normally consist of a metal chuck and a rubber insert matched to the capsize. Once a bottle is in place under the capping head, the chuck descends to apply consistent torque to each bottle and cap combination. Automatic chuck cappers may include multiple chucks to increase the capping machine speed. Handheld, semi-automatic, and tabletop chuck cappers will usually cap one bottle at a time. While one chuck and insert can handle different capsizes, a facility running both small and large-cap may require multiple chucks and/or chuck inserts. Chuck cappers are ideal for flat caps, but some modifications to the chuck and inserts allow for other screw-type caps to be run as well.

Snap Cappers & Lid Pressers

Snap cappers and lid pressers are both used for non-screw-type tops. Rather than being torqued onto the bottle, snap-type tops are simply applied using pressure and normally held in place by a lip on the container. The pressure is applied via a declined belt or a simple plunger depending on the application. Paint cans may work well in a lid presser, while plastic containers for some food and beverage products would use a press-on belt to avoid damaging the containers themselves. Snap cappers can be constructed very similarly to spindle cappers, with the spindle sets replaced by the decline belt, allowing snap caps to be sealed continuously as well, caps permitting. Spindle cappers and snap cappers can also be combined on one capping machine to handle an even wider range of cap types and sizes.

ROPP Capping Machine

A ROPP Capper (Roll On Pilfer Proof Capper) is somewhat of a speciality capper. ROPP cappers use specially designed knives to thread and seal tops onto containers. The most common product for a ROPP capping machine would be topping off a bottle of wine. Different bottle types and sizes may require different sets of knives when using this machine and this packaging machinery will not handle the variety of seals run by the spindle and chuck cappers. However, some ROPP capping machines can be manufactured to include a chuck-type capping head to expand the realm of caps that can be run.

Each of the capping machines discussed briefly above is available in different levels of automation, allowing this group of packaging machines to handle not just a wide variety of caps and bottles, but a range of production levels as well.
