you change laundry detergent lately? any hives? rashes?
i'd still buy new sterile bottles, and .45 whatman syringe filters.
pull the oil from a vial using an 18ga needle on a 10cc syringe. remove the needle. screw on a .45 syringe filter. push the 18ga back onto the filter. put a sterile 25ga needle into the top of a new, sterile 10cc stick the 18/10cc into the bottle and squeeze the oil through the filter into the clean vial. repeat for alllll your gear.
