[Histonet] RE: Defrost -80

[Jonathan Cremer]

Can't you obtain a replacement unit from your manufacturer for a week?

Otherwise, depending on the size and amount of the material to be stored, you could use dry ice in insulating boxes. That's not very user friendly though, and I wouldn't do it overnight unless someone stays to watch the amount of ice left.

We need to defrost our -80 freezer in a derm lab.  We do DIF procedures requiring the controls to be stored in the -80.  We don't have immediate access to another -80 freezer.  We do have a chest freezer that will maintain -20.  Can we hold those DIF controls at -20 while the -80 is down?  How long can those controls be stored that way without losing their IF?
