Whenever I am filtering my finished product into the sterile vial (I use an 18ga needle and a .45 filter), I usually get little pieces of rubber in the oil, presumably because the 18ga pins are so big. The pieces always sit at the bottom of the vial so I just toss the 1-2 ml that are left when it gets to the bottom, but is there a way to avoid this?? I suppose I oculd use something like a 22 ga to filter it in, but that would take FOREVER as I never make less than 50ml at a time. Would it be wise to invest in some crimpers so that I didn't have to do it like that?
