Ok so I've been thinking about the whole "neurotic level of sanitation" pretty seriously, I'm kinda thinking about it too hard...
Any pointers:
1) After measuring everything out and boiling it you pour the cooled solution into the vacuum filter.
2) Filter and here comes the first sterilization problem: sealing media bottle and extracting 10cc at a time. I know I can cook the bottle before and soak the top in alcohol so that after filtration the top would be sterile when it goes on and the solution would be sterile - until you take the top of. The air going in and out will not be sterile. Is this a real threat? The 10cc syringe IS sterile coming out of the wrapping for extraction from the media bottle I'm just worried about extraction.
3) Soak butyl stoppers in alcohol and cover the vials with aluminum foil and bake at 350-400' for 15-20 minutes. Do I need to soak vials in alcohol first to remove contaminates? Do I need to bake the butyl stoppers?
4) Once you have extracted 10cc of oil solution poke needle through foil into vial and release -sterile oil into sterile vial? Remove foil and place stopper - anything special here? Does it need to be dry or can traces of isopropyl alcohol be present?
5) Crimp flip top. Anything else?
I'm spraying all work spaces with sanitizer, placing plastic wrap and wiping with alcohol wipes. Latex gloves and hand sanitizer when I touch anything to prevent cross contamination.
Thanks
