A range of liquid refrigerators suitable for storing a number of samples where immersion into liquid nitrogen is permitted
How it works
Materials to be stored are placed in canisters which are suspended from the top of the unit. These are then immersed in the liquid nitrogen and the liquid nitrogen vapour.
The liquid nitrogen used in the refrigerators is supplied from a separate cryogenic storage vessel that’s filled by BOC CRYOSPEED on a regular basis. These vessels are available for rent from CRYOSPEED, helping to ensure all maintenance and legal responsibilities are carried out.

Note:
1 Evaporation rate and holding time are nominal. Actual rate may be affected by the nature of the contents, atmospheric conditions, container history and manufacturing tolerances. 2 Working time is an arbitrary, reference-only value to estimate container performance under the actual operating conditions 3 Without canisters. 4 The roller base increases the overall height of the vessel by 110mm.
