Globe Scientific's snap cap is designed specifically for use on flared-top urine centrifuge tubes and features a raised tab for easy removal of the cap. The cap snaps snugly onto Globe Scientific urine centrifuge tubes #112017, #112015 & #112030 and provides a great leak-resistant seal.
These 12-mL flared-top urine centrifuge tubes are made of high-quality polystyrene (PS) and are available in Ames-type, Kova-type and Whale-type styles. Blue and yellow snap caps are also available.
