How long can I keep bacterial glycerol stock in -20 freezer?

25 February 2019 1 10K Report

I need to prepare glycerol stock for bacteria and the only available option is to keep at a -20 freezer.

I would also like to know this. I have to repair our -80 freezer, so it needs to be defrosted first. How long would bacterial glycerol stocks be stable at -20C?
