Cryobiology and industrial gases – Preserving gas demand


Specifying a cryobiology storage system is an extremely important decision for any life sciences laboratory. A poor choice can put irreplaceable research at risk and also add unnecessary costs.

Two primary considerations are the temperature required at the top of the freezer and if the products are required to be immersed in liquid nitrogen (LN2) or stored in the vapour phase. Also, there is remarkedly better cell viability of products stored below the glass transition temperature of -130°C.

Two primary reasons to use vapour phase storage (storing above the LN2) versus immersing in LN2 are: the risk of cross contamination is reduced; and there is no dripping LN2 when the samples are then retrieved from the cryogenic freezer systems.

Customers can select from a wide range of cryogenic refrigerators and freezers. Both are double walled vessels with super insulation in the vacuum space.
