Should I store the cryopreserved cells in the liquid phase or gas phase of liquid nitrogen?
Description
In principle; both types of liquid nitrogen storage are acceptable; each having its advantages and disadvantages.
- Liquid phase storage provides a consistent temperature of -196°C; a longer holding time and a greater vial capacity but involves the risk of contamination issues.
- Storage in the gas phase is very safe with respect to contaminations but the holding time of the cells is shorter and the vial capacity is reduced.
