Does anyone have any clever techniques for either preventing or soaking up excessive condensation in culture vessels after they come out of the pressure cooker.

Does anyone else have this issue?

This seems excessive right?

I used to mop out each vessel individually with sterile paper towel corners and forceps. Now I leave them cracked open in my laminar hood for an hour or so. This just seems like I'm leaving too many opportunities for contamination.

Can leave them under the hood to cool a bit, usually no issue. I just leave the condensation be, I am not bothered fighting it so long as I can still see into the container. I have noticed those using gelrite get a bit less condensation (I use agar) but that may be anecdotal.

I think I must be doing something wrong then. Or maybe somehow it could be due to our excessive humidity here in Louisiana. I do leave them to cool in the hood. I have also tried leaving them in the cooker overnight. It's an excessive amount of condensation. To the point that it pools on top of the media and drowns the explant if I don't deal with it. I switched to gellan gum about a year ago. I like that you can spot contamination quicker with it.
