why are agar plates stored upside down

Re: why are agar dishes kept in a refrigerator until

Plates usually can last about a month if stored in the fridge whereas left out the plates will show signs of dehydration within a week or two If handled properly uncontaminated plates are still considered sterile after the agar is poured into them and of course they are stored inverted (upside down) to prevent bacteria from finding their way into the plate I've let plates sit out for
