If you draw up your oil based gear from a 10ml vial with an 18g needle will it make a hole so large that bacteria is more apt to get into the vial? I used a 23g but it was a real hassle to draw up for some reason... and i know you arent supposed to heat the whole amp so i dont see anything else i could do. I can get 18g needles though so what do you guys think?
