2 liter bottle gimmick

[Suzy]

I jerry rigged some IV filters awhile back, but when I got a bigger pump, I thought it was too much hassle. The cultures go for months, and I reuse the plates, so I didn't want o get that technical anymore. I'm not selling it, just using it as a hobbyist. But, if it were really important that the cultures stay really pure, you can make a filter out of a syringe, filled with floss.
