For my erlenmeyer flasks, I'm still using cotton and foil, but for my plastic flasks, that's not really an option. When I ordered some media from the OSB last year, they suggested the use of Nexcare Active Foam 3M bandages (the little round ones), which are autoclaveable and are supposed to do a good job. I gave them a try, but found that on my PP flasks, they would sometimes get moist and slide around during sterilization (and slide off of the vent hole).
I also have had a slightly higher rate of contamination with those flasks than my standard glass flasks, though they are treated the same, otherwise.
So, with my most recent order from Phytotech, I ordered some 3M micropore tape. Honestly, it just looks too thin. Maybe that's just me... but I'd only feel comfortable with the stuff if I had at least two or three layers of it over my vent
I notice that on some of the plasic flasks that I buy from other vendors (Chuck Acker, for example), there is a thin piece of material under the micropore tape covering the hole. What is that stuff? Feels a bit like teflon pipe-thread tape.
Of course the flasking patches that are available from Tissue Quick are supposed to be good, but they are not very cost effective.
What do the rest of you use?
Thanks!
