Sorry too so long to reply, working 12’s!
I put a septa cap and a high temp cap on media bottle. Then I would draw out 60cc at a time with syringes, then transfer to sealed sterile vials!
Side note. It took forever to draw out with a 18ga pin so I made a little hole in the septa cap so just the tip of the syringe fits in there tightly! You can pull the oil out way faster that way. It worked good.
If I’m going to continue brewing, I’m gonna look into a bottle top dispenser! There pricey so I’m not sure yet.
Hope this helps.
