Re: Cold Storage question



Can't remember the details, so I'm going to suggest you check the list
archives, but somebody wrote a while back that laboratory supply companies
offer the right kinds of freezers at cheaper prices than archival supply
companies.  They might have additional features, including the RH control
you were looking for.

The other thing I remember is that you need to be careful when removing
items from the freezer to see to it they are brought up to room temperature
slowly, I think to prevent condensation.  Might want to check the archives
on that one too.
