When I make mine I do the following

#1) I add food coloring to ID the different agar's Red for PDA, Blue for MDA, etc.

#2) I put it in 1 pint jars for storage. once it is made I put it in pint jars, put the lids on correctly, and Pressure Cook them. In essence I can it and seal it. The stuff will keep for ever that way.

#3) when I am ready to use it I PC the jar (Turning it back to a liquid and unsealing the jar) then pour plates in the glove box.

You can get petties of e-bay for cheep, I traded prints for mine on here.
