Just get some open top caps and some silicone septas to put own your media bottles and then you can draw from the bottle just like a vial with no exposure to outside elements. I also sterilize my vials with a small piece of foil over the top, after allowing the alcohol to evaporate. Then I just pierce the foil and inject the oil into the vial and leave covered until I'm ready to cap the vials.
Can you re-use the silicone septas more than once, like give it an alcohol bath? If you're only drawing out of it to transfer into the vials seems like a waste to use it just once?
