High-efficiency thermal insulation is critical for the safe handling and short-term storage of liquid nitrogen and other cryogenic coolants. Professional laboratory dewar flasks are engineered with double-walled vacuum insulation and robust protective jackets to minimize heat transfer. As a core component of our cooling range within heating and cooling technology, these vessels are essential for maintaining stable temperatures in sensitive research environments.
Why Choose Professional Dewar Flasks?
Our curated collection of cryogenic vessels is designed for technical durability and thermal precision:
- Robust Chrome Steel Construction: We stock Kundert Vario AG Dewar Vessels and Cryoson models featuring high-grade chrome steel jackets in capacities from 2 L to 6 L for superior physical protection.
- Secure Transport Solutions: Utilize KGW Schieder Dewar Transport Vessels (Type 26 B) with metal jackets and secure caps, available in 1.0 L and 4.0 L volumes for safe sample movement.
- Protective Metal Covers: Utilize KGW Schieder flasks with blue-coated metal covers, designed to provide enhanced durability for daily laboratory use.
- Versatile Geometry: Explore vessels in various dimensions, such as 7 x 235 mm, to accommodate specific laboratory setups and storage requirements.
LabFriend supplies dewar flasks from industry-leading manufacturers specialized in high-performance vacuum insulation technology:
- KGW Isotherm: The premier provider of KGW Schieder-branded transport vessels and blue-coated metal dewar flasks.
- Kundert Vario: Specialist in high-durability chrome steel AG Dewar vessels and specialized Cryoson storage solutions.
- Thermo Scientific: Leading manufacturer of high-end cryogenic storage and vacuum insulation systems.
Effective thermal management is the first step in successful cryopreservation; to further enhance your laboratory system, we recommend exploring these related categories:
- Cryogenic Storage Tanks: Use Cryonos high-capacity tanks for bulk liquid nitrogen storage before transferring to smaller dewar flasks.
- Cryogenic Racks: Organize your samples using Crystal Technology or Thermo Nalgene stainless steel racks within your large-scale cooling units.
- Cryogenic Boxes: Securely house your samples in LLG-Cryoboxes with customizable grid dividers for systematic organization.
- Cryogenic Tubes: Use Thermo Nunc or LLG polypropylene cryotubes for high-integrity sample containment during cooling.

Frequently Asked Questions
1. 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.
2. Can KGW Schieder transport vessels be used for long-term storage?
While highly insulated, these transport vessels (like the Type 26 B) are specifically optimized for safe sample movement and short-term holding; for permanent bulk storage, a dedicated cryogenic storage tank is recommended.
3. Are these dewar flasks compatible with liquid nitrogen?
Yes, 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.
4. Why choose a blue-coated metal cover for a dewar vessel?
The specialized 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.
