Any1 uses these? I'm looking into new ways of filtering, other than the conventional syringe filters (forearms are getting big...) . I'm concerned about the sterility of the bottle wich receive the filtrated solution; do you just draw the oil from the bottle and transfer it to vials? Like without any sort of 'rubber stoper' on the top? Also, what kind of membrane would you suggest (considering its .22um)
