Parafilm works best. You have to check out with a microbiologist and he will show you how to use the parafilm to seal plates. You will love it once you know how to do it correctly. The half an inch to 1 inch width cutouts should be held against the edge of the plate with left thumb and then using the right hand strech the tape as you paste it around the plate edge. The tape will stick and seal the plate very effectively. Best of luck Jay

Dear Experts, just have bought sealing tape for petri dishes at 35 euros per 33m roll. After unpacking, I realized that someone must earn a fortune by buying some cheap stuff in bulk and removing the label on the cardboard roll to prevent finding the real source. Any idea what I might try next time? Thanks for your help!
