CBS Isothermal -190°C Dry Storage Liquid Nitrogen Freezers.


 

Liquid Nitrogen Freezers - Dry Storage

CBS Isothermal Liquid Nitrogen Freezers feature a patented liquid nitrogen jacket to provide uniform storage temperatures in the -190°C range, free from liquid nitrogen contact.

This innovative Liquid Nitrogen Freezer Jacketed design eliminates the risk of cross-contamination through liquid nitrogen and the need for additional packaging to protect valuable cells and tissue.

With a minimal temperature gradient within the Liquid Nitrogen Freezer, the full internal volume of each freezer is available for storing samples at liquid nitrogen temperatures making the most efficient use of available capacity.

CBS Isothermal Freezers also provide added user safety by eliminating contact or splashing of liquid nitrogen whilst accessing your samples.

 

CBS Isothermal -190°C Freezers

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.

 


  • Medical Device Directive 93/42/EEC: 1993 Class IIA. 
  • Choice of 4 models offering capacities between 9,100 and 45,000 2ml vials (maximum).
  • All models feature the Series 2301 Auto-fill and Monitor System providing sample security and ease of operation.
  • A wide selection of inventory systems for vials and bags are available to complete the system.
  • Installation, commissioning and calibration service.

 

 

Liquid Nitrogen Freezer - Straw Storage Inventory System

Samples in straws have traditionally been stored in liquid Nitrogen. To help maintain samples at low temperatures when temporally removed for inspection and manipulation, straws are placed in small goblets (tubes), which retain liquid Nitrogen when they are taken out of the freezer.

However, to reduce the risks of cross-contamination and liquid Nitrogen contact, there is increasing interest to find an alternative approach.

The CBS LZ3-5G Inventory System for the V-1500 Isothermal freezer provides a unique and practical solution for storing and working with straws in the -190°C range, free from liquid Nitrogen.

 

•   Ideal for IVF and other straw storage applications.

•   Also suited to storage of vitrified samples in very small
    volumes (0,1 micro litre)

•   Isothermal Dry storage with uniform temperatures
    throughout the freezer from -190°
to -195°C.

•   3-level rotating carousel provides convenient inventory
    control and maximises storage
space. The system can
    hold up to 24,480*
straws in 68 canisters.

•  The middle and lower levels are ideal for medium and
   long-term storage respectively,
whilst the upper level
   can be used for storage
and as a workspace for
   viewing and manipulating
samples safely at -190°C.

•  Easy retrieval of samples using retrieval tool.
