Campys moving new house

My "CampyHouse" (a plastic candle jar) is gonna melt by the flame after a few weeks' usage, hence I need to find another substitution. It needs to be... 1. made of steel. 2. able to block air leakage. 3. large enough to contain more petri dishes than the current one, but small enough to fit in both 42C and 37C incubaters. I got another 25 cultures from Medlab (Campy x24, Salmonella x1), and I also suspect some factors such as antibiotics in media and temperatures may infect the groth of campys; therefore I went to the Warehouse near our campus and found 2 cake-alike stock pots which would meet my needs. Actually they look working perfectly. Their lids are made of transparant plastic(? maybe) and I just need to put them upside down so that the steel bodies come upward and won't have to be concerned about the candle flame. (so now they've got steel lids!). Furthermore, compare with the preceding candle jar, it's much easier to pack 24 petri dishes, which is more than 16 before! And don't forget they've got "transparant base" with them, so observing their groth without opening the container would also be possible as well (not quite sure yet though). With these merits, they cost just NZ$20 for both. It's really a bargain!! # New CampyHouses packed with... @42C: Charcoal selective agar ("CSA") plates from Medlab x6 (4 isolates/plate) Homemade CSA (with antibiotics added) x8 (3 isolates/plate) Homemade CSA (antibiotics not added) x8 (3 isolates/plate) @37C: Homemade CSA (with antibiotics added) x8 (3 isolates/plate) Homemade CSA (antibiotics not added) x8 (3 isolates/plate)
