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?
