Will a laboratory freezer be suitable for a slow freezing project?
I want to get some items and freeze them slowly. The more time the item spends between -2c to -5c the better.
Most domestic freezers do not go this high and I do not want to modify my freezer unless absolutely required. I thought of renting a lab freezer as these can be set to high temps e.g. -2c to -4c. However I am concerned that lab freezers are high performance and they may bring the items to say -4c in very quick times.
Is this the case or are lab freezers just as suitable as domestic freezers to slow freeze an item. I'd imagine that a lab freezer freezes fast when set to very low temps but then I wouldn't know and perhaps there is something i'm missing as I believe the freezer system can determines the rate of freezing.
Is a lab freezer suitable, if not why not, would a lab freezer bring an item to say -4c very quickly when set at that temp?
Thanks
