The Laboratory Dewar Flasks category includes the instruments, accessories and consumables needed to heat, cool, incubate, freeze or stabilise samples and processes at defined temperatures. Selecting them as part of a complete workflow helps prevent compatibility problems that are easy to miss when individual items are considered separately.
Temperature uniformity, recovery and control stability influence reaction rates, storage integrity and the reproducibility of many laboratory methods. The practical choice therefore depends on controller and logging options, working temperature range, heating or cooling capacity, and chamber or bath volume, as well as how frequently the product will be used and how it connects with the rest of the procedure.
A complete temperature-control setup matches the load and vessel to the working range, heating or cooling capacity, circulation, monitoring and safety requirements. This coordinated approach is particularly useful in research, biotechnology, pharmaceutical, food, materials and industrial laboratories, where repeatability and clear operating procedures matter. As part of the Laboratory Heating and Cooling Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Laboratory Dewar Flasks range
Our collection covers these dewar flasks compatible with liquid nitrogen, choose a blue-coated metal cover for a dewar vessel, benefits of a chrome steel jacket on a dewar flask, and kgw schieder transport vessels for long-term storage, giving laboratories practical choices for routine work and more specialised applications.
These dewar flasks compatible with liquid nitrogen
All professional dewar flasks from KGW Schieder and Kundert Vario are designed to safely contain liquid nitrogen (LN2) and other cryogenic liquids due to their high-performance vacuum insulation. Key differences are usually found in controller and logging options, working temperature range, and heating or cooling capacity. These details affect day-to-day usability as much as the main performance specification. Within the wider method, these products help laboratories hold samples and processes within the conditions required for repeatable work and dependable storage. They should be reviewed together with associated consumables, accessories and cleaning requirements.
Choose a blue-coated metal cover for a dewar vessel
The specialised blue coating on KGW Schieder metal covers provides an additional layer of protection against the laboratory environment and helps in quickly identifying cryogenic-specific equipment within the workspace. The most suitable format depends on working temperature range, heating or cooling capacity, and chamber or bath volume. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. This is especially valuable when teams need to hold samples and processes within the conditions required for repeatable work and dependable storage. Consistent handling also reduces the risk of variation between batches or operators.
Benefits of a chrome steel jacket on a dewar flask
A chrome steel jacket, as found on Kundert Vario vessels, provides exceptional mechanical strength and corrosion resistance, protecting the delicate internal glass vacuum flask from accidental impact and physical damage. When comparing options, consider heating or cooling capacity, chamber or bath volume, and uniformity and stability. The correct choice should fit the sample, expected workload and any equipment already used in the method. In practice, this supports efforts to hold samples and processes within the conditions required for repeatable work and dependable storage. It also gives staff a clearer and more repeatable procedure when multiple users or shifts share the same equipment.
KGW Schieder transport vessels for long-term storage
While highly insulated, these transport vessels (like the Type 26 B) are specifically optimised for safe sample movement and short-term holding; for permanent bulk storage, a dedicated cryogenic storage tank is recommended. Before ordering, compare chamber or bath volume, uniformity and stability, and pump flow or air circulation. A product that fits the complete workflow will generally be easier to validate, maintain and reorder. Within the wider method, these products help laboratories hold samples and processes within the conditions required for repeatable work and dependable storage. They should be reviewed together with associated consumables, accessories and cleaning requirements.
Featured brands
DWK Life Sciences is known for laboratory glassware, bottles and precision handling products, BRAND is known for liquid-handling products, volumetric labware and supporting accessories, VITLAB is known for plastic labware, dispensing products and chemical-resistant handling solutions, and JULABO is known for circulators, water baths and precise liquid temperature control. Compare each brand by controller and logging options, working temperature range, heating or cooling capacity, and chamber or bath volume, and check what is included with the product so the complete setup is clear before ordering.
Why choose LabFriend for Laboratory Dewar Flasks
Choosing laboratory dewar flasks often involves more than matching a size or model number. LabFriend's knowledgeable team can help you review controller and logging options, working temperature range, heating or cooling capacity, and chamber or bath volume and check how the product fits with existing equipment, samples and procedures. Our 100% online range keeps competitive pricing and lead-time information visible, while fast and reliable shipping across Australia supports both planned projects and routine replacement orders.
Explore laboratory dewar flasks as part of the complete laboratory heating, cooling and temperature control process rather than as a stand-alone purchase. Useful related areas include Laboratory Ice Flakers and Cryovials & Cryogenic Tubes for Labs, which can help complete the surrounding workflow. This approach helps laboratories align equipment, consumables and accessories while retaining the convenience of one online order and dependable delivery across Australia.

Frequently Asked Questions
Are these dewar flasks compatible with liquid nitrogen?
All professional dewar flasks from KGW Schieder and Kundert Vario are designed to safely contain liquid nitrogen (LN2) and other cryogenic liquids due to their high-performance vacuum insulation. Laboratories should compare controller and logging options, working temperature range, and heating or cooling capacity and document the selected setup for consistent use.
Why choose a blue-coated metal cover for a dewar vessel?
The specialised blue coating on KGW Schieder metal covers provides an additional layer of protection against the laboratory environment and helps in quickly identifying cryogenic-specific equipment within the workspace. For dewar flasks, also check controller and logging options, working temperature range, and heating or cooling capacity so the product fits the complete procedure.
What is the advantage of a chrome steel jacket on a dewar flask?
A chrome steel jacket, as found on Kundert Vario vessels, provides exceptional mechanical strength and corrosion resistance, protecting the delicate internal glass vacuum flask from accidental impact and physical damage. The final choice should reflect controller and logging options, working temperature range, and heating or cooling capacity, as these points influence day-to-day compatibility and repeatability.
Can KGW Schieder transport vessels be used for long-term storage?
While highly insulated, these transport vessels (like the Type 26 B) are specifically optimised for safe sample movement and short-term holding; for permanent bulk storage, a dedicated cryogenic storage tank is recommended. Laboratories should compare controller and logging options, working temperature range, and heating or cooling capacity and document the selected setup for consistent use.
How do I choose the right dewar flasks for my laboratory?
Review controller and logging options, working temperature range, heating or cooling capacity, and chamber or bath volume, together with expected workload and cleaning or maintenance requirements. A suitable product should fit the full method, not only the immediate task. Before ordering, confirm controller and logging options, working temperature range, and heating or cooling capacity and any accessories or consumables needed for routine use.
