    What Does a Lab Circulator Do?

    Laboratory circulators and chillers precisely control the temperature of deionized water, bath fluid, or PH-neutral buffer for delivery to integrated or external water baths, analytical instruments, incubators, and wet processing stations.

    What Is A Laboratory Circulator Used For?

    Lab circulators, common in life science research, drug discovery, material testing, wafer production, and wet chemistry, are used to cool or chill samples, thaw reagents or cell media, and supply temperature-controlled water to external equipment.

    Open vs Enclosed Lab Recirculators and Chillers

    Lab circulators and chillers include a fluid reservoir connected to a cooling or heating system regulated by a digital or analog controller. The integral reservoir, or water bath, may be open for easy access or enclosed by a gable cover to prevent heat loss. Certain circulators include a pump to deliver water to external equipment, such as refractometers, photometers, or viscometers.

    What Is A Laboratory Immersion Circulator?

    Immersion circulators are handheld systems designed to clamp onto water baths to regulate bath temperature.

    Immersion circulators include a cooling or heating coil, integral pump, and digital or analog controller to regulate temperature and flow rate.

    What is the Benefit of an Immersion Circulator Bath?

    Immersion circulators are economical alternatives to lab circulators or chillers, but do not include integral water baths and provide limited flow rates and cooling/heating capabilities.

    A - Lab Circulator Maximum Temperature
    (back to chart)

    Laboratory circulators and chillers include heating systems to precisely control the temperature of the water, buffer, or bath fluid.

    What is the Average Lab Circulator Peak Temperature?

    Lab circulators commonly heat fluid to 150°C.

    Julabo’s PRESTO circulators can achieve temperature set points up to 250°C. Common applications for heating circulators include food stability testing, medical device quality analysis, and forced aging studies.

    B - Lab Chiller Minimum Temperature
    (back to chart)

    What Lab Chiller Applications and Uses Are Most Common?

    Applications for lab chillers include cell freezing, blood banking, and pour point determination of petroleum products.

    What is the Lowest Achievable Lab Chiller Temperature?

    Laboratory chillers, or refrigerated circulators, include cooling coils to chill bath fluid or lab-grade water. Lab chillers commonly cool fluid down to -20°C.

    Julabo’s PRESTO circulators can maintain temperatures down to -80°C.

    C - Lab Circulator Capacity
    (back to chart)

    Lab circulator capacity refers to the volume of liquid safely stored and processed by the system.

    Lab Benchtop Chiller Capacity

    Julabo’s Cryo-Compact chillers are low-throughput benchtop chiller systems that accommodate fluid volumes under 10 liters.

    Free Standing Lab Circulator Capacity

    Julabo’s FL Series circulators are high-throughput, free-standing systems that accommodate fluid volumes up to 50 liters.

    D - Voltage
    (back to chart)

    120-volt connections are suitable for standard laboratory power outlets in the United States, Canada, Mexico, and South America.

    208-volt or 240-volt connections, common in Mainland Europe and throughout Asia, require less current (amperage) and smaller conductors than equipment designed to operate at 120-volt.

    E - Lab Circulator Configuration
    (back to chart)

    E1 - Immersion Circulator

    Immersion circulators, like Julabo’s CORIO C Series, are placed within external water baths to mix and precisely control the temperature of the bath fluid. Immersion circulators are more cost-effective than benchtop circulators and more flexible: one immersion circulator can control multiple water baths within a single lab, given the baths aren’t operated simultaneously. However, immersion circulators cannot achieve the flow rates and temperature ranges of a benchtop circulator.

    E2 - Open Bath Heating Circulators

    Open bath circulators, like Julabo’s CORIO CD Series, include an integral, exposed water bath regulated by a digital controller. Open bath circulators provide easier sample access than enclosed bath circulators but may be prone to heat loss or larger temperature fluctuations. Common applications include temperature control of measurement cells, heating glassware, and material testing.

    E3 - Recirculating Chiller

    Recirculating chillers contain enclosed water baths, cooling and/or heating coils, and digital control systems. Recirculating chillers include pump systems to deliver fluid to external equipment, such as wet processing stations, water-jacketed incubators, photometers, and refractometers. More expensive than immersion or open bath circulators, recirculating chillers provide large bath capacities, higher flow rates, broader temperature ranges and tighter set point tolerances.

    F - Lab Bath Tank Material
    (back to chart)

    F1 - Polycarbonate Lab Bath

    Transparent polycarbonate baths are more cost-effective and provide better sample visualization than stainless steel baths. However, polycarbonate baths support limited temperature ranges, typically between -20°C and 100°C.

    F2 - Stainless Steel Lab Bath

    Stainless steel baths help maintain aseptic conditions, resist acids and solvents, and support broader temperature ranges than polycarbonate baths.

    G - Lab Circulator Power and Wattage
    (back to chart)

    Lab circulator power, listed in Watts (W), corresponds to the heat load capacity of the system.

    Heat energy removed or applied to the fluid drives the maintainable temperature range of the system. Common lab circulators feature heat loads between 250 and 2,000 Watts.

    Julabo’s PRESTO circulators include heat loads up to 2,700 Watts and, thus, industry-leading temperature ranges (-80°C - 250°C).

    A – Application: Which Desiccator is Best for My Application?
    (back to chart)

    Cost vs. Control: Terra Desiccators Simplify Your Choice

    You need to protect sensitive samples, but you don’t want to overpay. Below is a list of application descriptions to help choose the best desiccator storage system for your application and budget.

    A1 - Critical Control Demands:

    For applications that require not only a low-RH set point, but a system that recovers it quickly when doors open/close, allows a different set point in each chamber, and/or protects against static and particulate contaminants.

    Stainless steel nitrogen desiccator cabinet, 6 chambers with automatic humidity control

    Typical Applications

    • Low exposure tolerance: Microelectronic or pharmaceutical samples that degrade very quickly when exposed to moisture.
    • High access frequency: Doors open/close before system can recover target set point level.
    • Exposure testing: Requires a separate %RH monitor/control in each desiccator chamber.
    • ESD-sensitive parts: Minute static discharge results in severe degradation, cuts yields.
    • Sterile and/or Particle Sensitivity: Critical contamination requirements won’t tolerate materials that shed particles or corrode.

    A2 - Moderate Control Demands:

    Sensitive samples may require automatic low humidity set point control, but low access frequency minimizes the need for faster RH recovery time. Protection against ESD and/or particulate contaminants may also be required.

    N2 desiccator cabinet with automatic humidity control

    Typical Applications

    • Low-Moderate exposure tolerance: Low humidity and automatic monitoring is required. Microelectronic or pharmaceutical samples that degrade when exposed to moisture.
    • Moderate-High Access Frequency: Parts are accessed on a daily basis and/or are sensitive to moisture exposure when doors are opened.
    • ESD-sensitive parts: Minute static discharge results in severe degradation, cuts yields.
    • Sterile and/or Particle Sensitivity: Critical contamination requirements won’t tolerate materials that shed particles or corrode.

    A3 - Minimal Control Demands:

    You need occasional nitrogen purging or desiccant to bring down the RH, or you may only need a dust-free enclosure without humidity control.

    Static-safe desiccator cabinet in SDPVC with 8 chambers and adjustable shelving Typical Applications
    • Moderate-High exposure tolerance: Low humidity and/or automatic monitoring is not required.
    • Low Access Frequency/Extended Storage: If low humidity is required, fast recovery time is not, because doors are rarely opened: you stock the sample and come back for it days or weeks later.
    • Moderate Static Protection: Availability of static-dissipative materials a plus, but ionization not required.
    • Dust-Free Conditions: Samples require a clean environment, but chrome plating and adhesive seals are acceptable.

    Additional Application Considerations:

    For critical moisture control applications, relative humidity (RH) set-point recovery time is one of the most important considerations to achieving the required quality, safety, and shelf life of stored materials.

    RH recovery is the time needed to reach an RH set point after a desiccator chamber or cabinet is accessed. A fast RH recovery time minimizes exposure of stored materials to harmful moisture levels. Thus, the ideal desiccator quickly and efficiently reaches and maintains the desired RH level.

    Set-point recovery time depends on several variables listed below. Keep these factors in mind to choose the best desiccator storage system for your application and budget.

    • Internal & External RH:

      The desired internal RH set point depends on industry and application. Extremely low humidity requirements (under 10% RH) are more difficult to achieve and generally call for a Smart controller option to optimize recovery time and efficiency.

      The greater the gap between required internal RH and ambient RH, the more time and inert gas will be needed to remove moisture from inside the desiccator. For example, a desiccator in a more humid ambient environment will have more moisture in the air to displace, and will therefore require more nitrogen gas or a more efficient humidity control system than one in a less humid environment.

    • Access Frequency & Duration:

      RH set-point recovery time is affected by the need to access parts inside the desiccator cabinet. Each time a door is opened, moisture-laden air, often bearing particles, enters the exposed chamber. The longer a door is left open, the more ambient air can flow inside. Once the door is closed, depending on the cabinet design, moisture can migrate from chamber to chamber, raising the internal RH throughout the cabinet.

      During periods of frequent or prolonged access, a poorly configured desiccator may never attain the required RH set point, posing a serious threat to quality, safety, or shelf life of stored materials.

      Choosing an appropriate automatic RH control system and cabinet design will help mitigate problems caused by frequent access.

    • Desiccator Cabinet Size & Chamber Configuration:

      The size or volume of your desiccator will determine how much ambient air needs to be displaced to reach your target RH set-point. Thus larger desiccators typically require more nitrogen or a more efficient RH control system, than smaller ones.

      Furthermore, the chamber configuration can have a significant effect on time to reach set-point. Isolated chambers tend to be more efficient, as opening one chamber will not expose other chambers in the cabinet to ambient air. Non-isolated chambers that share the same air space will generally take longer to recover after one door is opened, as ambient air can more easily circulate through the entire cabinet.

    • Nitrogen Gas Expense:

      Users seek to achieve a low RH set-point as efficiently as possible to reduce wasteful gas consumption. Unfortunately, unassisted RH control systems require significantly higher consumption of nitrogen gas to reach the desired relative humidity set-point. This problem compounds with high access frequency.

      High nitrogen gas consumption drives up overhead cost and can lead to other operational problems. For instance, those who rely on gas canisters will need to plan for more frequent replacements and will be suseptible to dealing with supply shortages.

      A smart control system automates the process to conserve nitrogen and reduces costs by up to 78%. A nitrogen generator can also eliminate the supply shortage issues from dependence on pre-filled gas canisters.

    • Cabinet Material Type:

      Material type can also affect relative humidity inside a desiccator cabinet. The more porous or hygroscopic a material, the easier it is for gases and moisture to transfer through. Many plastics such as acrylic may appear impermeable to the naked eye, however are porous enough at a molecular level to absorb moisture that can then permeate into the chamber. The diffusion or passage of moisture through acrylic can occur in a few ways listed below. The higher the difference between moisture levels, and the greater the exposed surface area, the higher the rate at which moisture will enter the chamber.

      1. Walls inside the cabinet can absorb moisture from ambient air already inside the cabinet, and then release the moisture after the cabinet is purged with a dry inert gas.
      2. Moisture can permeate through the walls from the outside (higher moisture) to inside (lower moisture).
      3. Walls can absorb moisture from direct contact with water (either inside or outside the cabinet).

      Critical moisture control applications concerned with moisture vapor transmission rate (MVTR) should consider a vapor impermeable cabinet material such as stainless steel to achieve the required quality, safety, and shelf life.

    B – Nitrogen RH Control Systems:
    (back to chart)

    Desiccator airflow diagrams

    B1 – Nitroplex™ System: NitroPlex™, Terra’s most efficient humidity control solution, is designed for the most demanding critical moisture control applications. The system features multiple RH sensors modules to allow RH monitor & control to 0% RH in each isolated chamber. The modules use automatic binary (on/off) valves to quickly and efficiently direct N2 gas where and when it’s needed. The ability to establish separate humidity set points in each storage chamber allows for storage of parts with differing moisture sensitivities and conservation of N2 gas in chambers that are not in use.

    B2 – IsoDry® System: IsoDry® upgrades the Dual Purge™ & NitroWatch™ system by adding twin dilution fans for drastically improved RH recovery & uniformity. The fans rapidly mix and circulate incoming nitrogen gas to accelerate moisture removal and achieve uniform RH throughout the entire cabinet. The door sensors de-activate the dilution fans when a door is open to minimize the spread of incoming moisture and contaminants throughout the cabinet.

    B3 – Dual Purge™ & NitroWatch™: This system is designed for larger cabinets. Like the Smart® system, it features a single RH sensor for automatic RH set point control to 0%RH. The Dual Purge™ has two gas flow settings (high/low) to rapidly reach and then maintain the user-specified set-point. Door sensors trigger high gas flow when doors open to help protect against the entry of contaminants, and expedite set-point recovery. Because this system includes only 1 RH sensor, the displayed RH reading may not accurately reflect the RH in other chambers of the cabinet.

    B4 – Smart® System: Terra’s Smart® desiccator system features a built-in RH Sensor to provide automatic RH set point control to 0% RH with binary (on/off) gas flow. The automatic RH set point control minimizes necessary supervision and increases efficiency of N2 gas consumption. The system is recommended for smaller cabinets with 1-2 chambers. This single gas inlet system can encounter inefficiencies with gas distribution and RH uniformity in larger cabinet systems.

    B5 – Flow Meter: A manually controlled flow meter offers the lowest up-front cost for RH control. It is most suitable for smaller desiccators that do not require much nitrogen gas or those that require minimal supervision. Manual control means humidity control is more prone to human error and not as efficient with the consumption of inert gas, which can lead to damaged products and high operating costs.

    C – Cabinet Design
    (back to chart)

    C1 – Isolated Chambers: One way to improve moisture control and recovery is to compartmentalize a cabinet into isolated chambers. The multiple air spaces are thus independent and RH in one chamber is unaffected by access to adjacent chambers.

    C2 – Rear Plenum for Improved Gas Distribution: Larger desiccator cabinets with single gas inlets are more susceptible to RH control problems caused by uneven gas distribution. A rear distribution plenum helps alleviate these problems. Instead of feeding a gas line directly into 1 chamber, the gas inlet feeds into a narrow wall plenum adjacent to all chambers. The plenum pressurizes and simultaneously distributes gas through small perforations in the wall to every chamber in the cabinet. Distribution plenums also allow for isolated chambers (mentioned above).

    C3 – Requires Automatic Relief/Bleed (RB) Valve(s): RB valves provide continuous pressure relief while also functioning as a one-way check valve. Installing one on each chamber improves moisture and contamination control. Any contaminants that enter through an open door can exit out the same chamber without migrating to other areas. Desiccator cabinets with isolated chambers require one RB valve per chamber to safely de-pressurize and ensure rapid RH recovery.

    C4 – Reinforced Doors with One-Piece Fused Gaskets: This seemingly small detail makes a big difference, as it is one of the most common features likely to break or malfunction on a desiccator cabinet. An unidentified leak or non-functioning “out of service” desiccator cabinet in a worst case scenario can lead to an extremely costly loss of materials. Through 40 years of refinement and attention to detail, Terra’s desiccator cabinets have been designed and tested to perfect this important feature for guaranteed long-lasting, easy to maintain, and reliable operation.

    Desiccator cabinets reinforced with stainless steel frames lend rigidity for an improved seal, and extend the service life of the entire cabinet. Heavy-duty lift latches easily close to produce a strong seal and prevent metal-on-metal scraping common with rotary latches. The ergonomic design also minimizes stress on your wrists and pinching of fingers. Optional locking lift latches are also available (specify one per chamber). The door frame is lined with a one-piece durable, resilient, and chemical resistant “e” shaped rubber gasket. This flexible gasket compresses to provide a tight seal and is mechanically attached to the door so it won’t slip, peel, or deform over time. The doors are also completely removable for further cleaning, maintenance or repair.

    D – Cabinet Materials
    (back to chart)

    D1 – Clear Acrylic (Plexiglass): Low cost and lightweight acrylic offers durability (17x impact resistance of glass) and superior clarity. The transparent walls help quickly find items anywhere inside, even those hiding in the back or bottom of the cabinet. Acrylic’s two main drawbacks (hidden costs) are low chemical resistance (acrylic is damaged by alcohol and many other cleaning agents), and poor protection from electro-static discharge (ESD).

    D2 – Amber Acrylic: Amber acrylic adds to the benefits of clear acrylic by filtering out UV and blue light to protect light sensitive materials from degrading, or changing composition. Similar to clear acrylic, it shares the same two drawbacks: low chemical resistance and poor protection from ESD.

    D3 – Static-Dissipative PVC (SD-PVC): SD-PVC not only dissipates static charges safely but also eliminates the particle attraction that static charges create. Surfaces stay clean, inside and out, making this material perfect for use in cleanrooms. SD-PVC is transparent and highly durable, it can be used in place of acrylic in nearly any application. It features a surface resistivity of approximately 10^7 ohms per square and is completely non-contaminating—with no measurable outgassing—and it resists a wide range of chemicals such as alcohol and other common cleaning agents.

    D4 – Stainless Steel: Stainless steel desiccator cabinets have many benefits. They are ideal for heavy duty storage applications of large, bulky materials. Stainless steel is also suitable for sterile applications. It resists most harsh chemicals and alcohol-based cleaning agents, and won’t produce contaminants during sterilization. Lastly, unlike plastics, stainless steel is impermeable to moisture and therefore suitable for the most critical low humidity storage applications.

    Terra offers 304 and 316L stainless steel. 316L-grade contains more nickel and molybdenum than 304-grade, enhancing its resistance to corrosion in wet environments, degradation from bleach-based disinfectants, and high-temperature sanitation, like autoclaving.

    D5 – Electropolish Service: Electrochemical polishing improves the surface finish of stainless steel for increased chemical resistance, to support easy sterilization and reduce micro-cavities where microbes can colonize.

    E – Other optional Accessories
    (back to chart)

    E1 – Nitrogen Generator: Compact and portable nitrogen generators eliminate the need for costly nitrogen gas cylinders and minimizes the risk of unplanned supply shortages. They provide complete control over rate and purity of nitrogen gas from 95% to 99% purity.

    E2 – Ionizing Modules: Ionizers can be installed into the rear gas distribution plenum of a desiccator cabinet to help neutralize electro-static surface charges throughout a desiccator cabinet.

    E3 – Locking Lift Latches: Locking Lift Latches help prevent unauthorized access to sensitive or valuable materials. Different keys can be assigned to each chamber for added security. Chambers can be further reinforced with locking brackets (for padlocks) and tamper-proof hinges.

    F – Number of Chambers
    (back to chart)

    Terra stocks standard chamber configurations for each line of desiccators. In general, larger desiccators typically require more nitrogen or a more efficient RH control system, than smaller ones.

    Lab ovens are used to dry gently thaw frozen samples, cure composites and prepare raw materials. Commonly used in environmental labs, biotechnology facilities, pharmaceutical drug development, forensics labs, and raw material manufacturing plants, ovens are designed for general lab use or specialty applications, such as cGMP areas, ISO-rated cleanrooms, or fire-rated spaces.

    A1 - Forced Air Ovens

    Forced-air ovens utilize blowers located in a side-mounted or rear-mounted plenum to circulate high-velocity air across the sample storage chamber. The high-powered fans increase the air change rate within the internal chamber, to protect sample batches from cross-contamination, and optimize the heat transmission between air and sample. Forced-air ovens are commonly used to heat HPLC samples or rapidly dry glassware, such as beakers, Erlenmeyer flasks, and graduated cylinders.

    A2 - Gravity Ovens

    Gravity-convection ovens, which do not include a blower, are economical alternatives to mechanical-drying or forced-air ovens. Used primarily for general sample drying or material baking, gravity ovens must be closely monitored to ensure that cold spots or stagnant air zones don’t develop in corners of the internal chamber.

    A3 - Mechanical Ovens

    Mechanical-convection ovens utilize a blower or fan to circulate air throughout the internal chamber. The boost in air change rate supports faster recovery times after the door is opened and better temperature uniformity across the sample storage area.

    What is the Difference Between a Mechanical and Gravity Oven?

    Unlike gravity ovens, mechanical ovens are not prone to develop cold spots or stagnant air zones. However, mechanical ovens demonstrate lower temperature ramp rates and recovery times than forced-air ovens.

    A4 - Vacuum Ovens

    Vacuum ovens connect to an external vacuum pump to create a negative-pressure area within the sample storage chamber. An exhaust port vents moist and contaminated air away from the samples and through a filter for safe release.

    What Are Vacuum Ovens Used For?

    Vacuum ovens are commonly used for moisture determination, sample outgassing, desiccant regeneration, and hazardous sample processing.

    B - Maximum Lab Oven Temperature
    (back to chart)

    Standard laboratory ovens maintain temperatures ranging from ambient to 300°C.

    High-temperature ovens utilize specialty heating elements and additional insulation to reach temperatures up to 400°C. Generally speaking, as the capacity and size of the oven increases, the maximum achievable temperature decreases. The lab oven’s intended use will define the required temperature range. For instance, curing and annealing processes commonly require heating to 250°C while glassware sterilization requires heating to 160°C.

    C - Oven Capacity
    (back to chart)

    Compact, research-use lab ovens include 1 to 3 cubic feet of sample storage space.

    Standard-capacity lab ovens commonly include between 4 and 9 cubic feet of internal storage space. High-capacity ovens boast sample storage capacities up to 28 cubic feet.

    Terra’s Universal’s high-capacity, cleanroom-compliant oven includes 67 cubic feet of storage space and HEPA filtered air supply.

    D - Lab Oven Voltage
    (back to chart)

    120-volt connections are suitable for standard laboratory power outlets in the United States.

    208-volt or 240-volt connections require less current (amperage) and smaller conductors than equipment designed to operate at 120-volt.

    E - Digital vs Analog Lab Oven Controls
    (back to chart)

    E1 - Analog Lab Ovens

    Analog laboratory oven controllers include manual timers and temperature set point dials mounted on the front panel of the oven for convenient access. More economical than digital controllers, analog systems don’t include data export, interlocking doors, or digital, LED readouts.

    E2 - Digital Lab Ovens

    Digital laboratory oven controllers include an LED readout displaying current conditions, temperature set points, and programmed drying times. Certain digital controllers include over-temperature protection, open-door alarms, secure data export (for cGMP labs) and electronic door locks.

    F - Laboratory Oven Material
    (back to chart)

    F1 - Painted Steel

    Painted steel ovens are durable, long-lasting, corrosion-resistant, and able to withstand large fluctuations in ambient temperature and humidity. Common in manufacturing or general lab settings, painted steel ovens are commonly used for glassware drying, material stress testing, adhesive bonding, or glass annealing.

    F2 - Stainless Steel

    304-grade stainless steel lab ovens are is rigid, chemical-resistant, easy to disinfect, and maintain aseptic conditions within the lab. Stainless steel ovens are used primarily for electronics testing, circuit board production, petri dish sterilization, substrate adhesion, and forensic fingerprint analysis.
