Freezer programmable

To oppose the freezer programme goes against the tenets of the Free World, proclaims Ettinger, and any such opposition is symptomatic of a mind warped by totalitarian ideology, believing that the individual is of less importance than the race, the state or society. 

In order to use a programmable freezer it is essential to have a supply of piped liquid nitrogen from a pressurised cylinder and this is also very convenient for topping up liquid nitrogen freezers. 

Complete 96 well microtitre plates and their contents can also be frozen in a programmable freezer. The medium in the wells should be replaced with freezing medium ( 7.3.1) and the whole plate cooled on ice and taped shut and wrapped in plastic film prior to freezing.
