OK fellas for you that have read this now you see why i bake. I also bake at 280 or so normally. the stoppers will not melt if the rack is lowered in the oven well away from the top. let the oven preheat then place vial/vials in oven for a minimum of 1 hour. Turn the oven off and let cool to room temp before removing product. Make sure to calibrate you ovens from time to time with a thermometer. If you do study this out you will find some data showing that 340f for 2 hours is needed. After working in the Pharm business for several years, for our application, this is not necessarry. All of the numbers the labs have determined are on the high side just to be safe. I have always recommened 250-275 with emphasis on 275.
we have already determined that BA is a preservative and not a sterlizing agent in previous discussions. Pressure filtration in conjunction with heat sterlization is the safest route we have to making a sterile product for Sub-Q, IM injection or depot. Now this just applies to oily solutions/suspensions. Aqueous solutions/suspensions normally require autoclaving in conjunction with antimicrobials.
hope you guys found this intersting and that all read it who are considering home brewing. There some nasty stuff out there that can cripple or kill if it is injected into your body. Be smart and play it safe. .
