Liquid nitrogen is, like all liquids, a possibleDewar transporter of contaminants.
Contamination between samples, leakage of liquid nitrogen into sample vials during storage and contact of liquid nitrogen with skin are just some of the risks that can be eliminated with an Isothermal liquid nitrogen dry storage freezer.
CBS Isothermal Freezers: No liquid nitrogen contact
Models: CBS Isothermals
This new storage system uses the same vacuum insulated vessel as conventional ln2 freezers, but instead of the liquid nitrogen being in the sample storage space of the freezer, it is in a patented liquid nitrogen jacket in the wall of the freezer.
This liquid nitrogen jacket produces a unique vapour circulation in the freezer, in combination with the convection from the freezer walls, produces a very stable temperature in the -190ºc range without the large vertical temperature gradients found in traditional vapour phase ln2 storage tanks.
The minimal temperature gradient and lack of liquid nitrogen in the bottom of the vessel means that the full internal volume of each freezer is available for storing samples at liquid nitrogen temperatures, making the most efficient use of capacity.
The Isothermal Concept
The sample storage area is cooled by a liquid nitrogen jacket surrounding the stainless steel interior, and by nitrogen vapour entering the freezer from the jacket via directional vents. This patented technology provides exceptional temperature uniformity in the -190°C range, allowing the full freezer capacity to be used with confidence. The circulation of vapour within the freezer also results in less cold air loss during lid opening and improved visibility. This allows full-width lids to be used providing quick, unrestricted access to sample racks.
No Liquid Nitrogen Contact
With no liquid nitrogen in the storage area, samples can be stored safely in the -190°C range without the risk of cross-contamination through liquid nitrogen. The Isothermal design also provides added user safety with no splashing or contact of liquid nitrogen when removing racks and samples from the freezer.
Isothermal Freezers feature the Series 2301 Auto-fill and Monitor System, which controls the automatic filling of the liquid nitrogen jacket and provides the user with an easy to read overview of the freezer temperature and status.
A comprehensive alarm system with remote alarm contact constantly monitors all aspects of the freezer’s operation. Samples are also protected by lid and control panel locks. The freezer can be monitored by a central BMS or monitoring system.
A wide selection of inventory systems for vials and bags are available to complete the system and optimize sample storage.

Straw storage inventory system - Available for straw holding facilities
Designed for the CBS V-1500AB and V-3000AB Isothermal freezers, this patent-pending inventory system provides an efficient solution for storing and working with straws, free from liquid nitrogen contact. -195˚C -190˚C
Rotating carousels provide access to lower storage levels and maximise storage space.
The upper level provides a convenient workspace where canisters can be parked and samples inspected at -190ºC. Use the retrieval tool to place and retrieve canisters quickly and easily.
