frost-free

[Brick Ayola]

Greetings!
I recently entered a laboratory that was storing molecular biology 
reagents in a -20C frost-free freezer. Among the items were expensive PCR 
polymerases <shudder>. I obtained "coolers" designed for 
the storage of enzymes. However, problems remain with PCR results. Should 
I unplug the frost-free and let it free-fall down the stairs or is there 
anything safely stored in a frost-free freezer? If I should empty the 
frost-free, is it acceptable to store everything at -80C? (except of 
course enzymes). Thanks for your advice.
