Isothermal FreezersPatented LN2 Jacket Technology
Isothermal Liquid Nitrogen Freezers with exclusive technology for superior sample integrity.
Our isothermal liquid nitrogen freezers are built with our patented jacket technology designed to provide you with superior sample integrity. LN2 is stored in the jacketed space that surrounds the chamber, so the storage area is completely dry and has industry-leading temperature uniformity.

Isothermal Liquid Nitrogen Freezers with exclusive technology for superior sample integrity.

Our isothermal liquid nitrogen freezers are built with our patented jacket technology designed to provide you with superior sample integrity. LN2 is stored in the jacketed space that surrounds the chamber, so the storage area is completely dry and has industry-leading temperature uniformity.

Our proprietary Isothermal Technology delivers unmatched temperature uniformity.
Samples stored in our jacketed isothermal freezers are completely isolated from contact with liquid nitrogen, which is contained in a space between the inner chamber and middle walls of the freezer. The Isothermal’s LN2 layer blankets the wall of the storage area to produce temperature uniformity not possible in ordinary liquid nitrogen freezers.
Contactless freezing greatly reduces the chance of sample cross-contamination, eliminates the risk of liquid nitrogen leaking into samples, increases staff safety, and provides more storage space when compared to traditional liquid nitrogen freezers.
Industry Best Temperature Uniformity, with storage temperature variation of less than 6ºC from the top to the bottom of the chamber.
More Storage Space
Patented jacket technology provides more storage space than traditional LN2 freezers because there is no LN2 at the bottom of the chamber. Traditional LN2 freezers have at least six inches of LN2 pooled at the bottom of the storage area.
Reduced Contamination Risks
Studies show that viral, bacterial and fungal pathogens can survive after suspension in liquid nitrogen. By eliminating liquid in the storage area, our dry freezers greatly reduce the possibility of cross-contamination by infected samples.
Cryogenic Capable, enabling storage temperatures to be set as low as -193ºC.
Advanced Sample Protection
Storage in liquid nitrogen can make vials shrink. Shrinkage can cause LN2 to seep into the vials, which on re-warming, can expand and subsequently explode as nitrogen vaporizes inside the vials. Dry storage eliminates this possibility.
Increased Safety
Our exclusive jacket design provides ehanced safety by eliminating contact with or splashing of liquid nitrogen.
Isothermal Freezers are offered in two configurations; the standard V Series, and the Carousel models, designed for use with ceiling height restrictions.
V Series Isothermal Freezers
Features wide lid opening that makes it easy to see all of your racks at once and quickly retrieve the one you need. Quick rack retrieval time minimizes exposure time to ambient temperatures and helps to ensure a consistent storage temperature.

Carousel Isothermal Freezers
Designed for ceiling restrictions, the carousel isothermal freezer features a motorized carousel and rectangular lid opening, which gives you quick and easy access to the rack you need without having to move other racks out of the way. Quick access means less exposure to ambient temperatures and lower LN2 costs.
