Butyl Vial Stoppers
20mm butyl rubber stoppers for our 10ml and 20ml glass vials. Press a stopper into the vial neck, then crimp a 20mm flip off seal over it for a tight, tamper-evident closure. The rubber reseals after a needle passes through, so you can draw from the same vial more than once. Sold in 10, 25 and 50 count sets.
Orders placed by 3pm ET, Monday through Friday, ship the same day from the USA. New to stoppers and seals? Read our guide: How to Use Flip Top Vial Seals and Rubber Stoppers.
