Yeah get a whatman .45, a sterile vial, a 20ml syringe and two 18g pins. Clean the sterile vial with an alcohol pad and put both 18g pins in it. One to vent and one for the filter. Stick the filter on one of them. Draw your gear to be filtered in the 20ml syringe and attach it to the filter on the other vial. Push it through to filter. Done.
