storage of culture plates - (May/11/2013 )

I am wondering why my culture plates (agar plates fresh or inoculated either with bacteria or yeasts) become filled with moisture when stored at refridgerator even though they are well wrapped with parafilm ? Anybody knows a solution ???

Hello,

Do you store your plates inverted? If not, then that might be the reason.

Yes I do while incubation. I don't know whether this matters while storing at 4C.

Because condensation will accumulate on the lid instead on the agar, limiting the posibility of losing the culture
