Storing Stem Cells in Liquid Nitrogen or Vapor

There are two different ways to store stem cells: in “full liquid” (that means that the tank is full of liquid nitrogen at -190º Celsius) or in “vapor” (that means that the specimens are not in the liquid, but rather in the vapor from the liquid, stored at -130º Celsius). There are pros and cons to each storage method, but the industry standard is changing to vapor.

Although temperature maintenance used to be better in full liquid, new storage tanks have been significantly improved and now vapor tanks are able to maintain a consistent temperature throughout the tanks.
