PURE EXTRACT said:Words from a very wise friend:
"Make sure you filter that fina through a 0.2 micron filter..."
"Remember some strains of staph can get through the 0.45 micron filters that come with the kits. Also, alcohol and heat will not kill the staph spores so excess BA content or baking your stuff in the oven will not sterilize it. You can get two filters and 3 50 mL sterile vials for like 20 bucks delivered from getpinz.com."
The point about the spores is moot since a 0.22 micron filter is nowhere near small enough to trap them; consider spores to be much to small to remove by filter at home.
