antibiotic stability in plates at room temperature? - (Nov/14/2008 )

for freshly made plates containing carbenicillin/chloramphenicol, how long are these stable at room temperature? i know they're supposed to be stored at 4 deg, but would they be alright if left out overnight on the benchtop?

Fine for a week. No prob. Better to seal with parafilm though.
