Patented isothermal LN₂ jacket technology

CBS Isothermal Freezers use a patented liquid nitrogen jacket to deliver uniform storage temperatures in the -190°C range. Instead of storing samples directly in liquid nitrogen, LN₂ is contained in the freezer wall, creating a dry storage space that helps protect samples and users.

No liquid nitrogen contact

The dry-vapour design helps eliminate risks associated with traditional liquid phase storage, including cross-contamination through liquid nitrogen, vial shrinkage and potential exposure of users to LN₂ splashing when retrieving racks and samples.

Superior sample protection

The isothermal design supports excellent temperature uniformity from top to bottom, allowing the full storage capacity to be used with confidence. This makes the V-3000AB-ST suitable for high-value samples requiring stable long-term cryogenic preservation.

Rack configurations

Organizing the space in your freezer can help make laboratory workflows more efficient. Effective sample management can result in both cost and time savings while improving accessibility and organisation within the freezer.

By choosing the right rack configurations, not only can operational efficiency be increased, but the risk of sample degradation caused by exposure to ambient temperatures can also be significantly reduced.

This is especially important when storing valuable stem cells, cord blood, bone marrow or other sensitive cell and tissue samples that require reliable cryogenic preservation.
