Product Details
Wheaton® 20mm seal is made of aluminum and features a center tear-out design that is unlined. This open top seal includes an opening to provide exposure of the vial's stopper or septa (not included). The center disc tear-out seals allow for a tear-away center disc, converting the seal into a hole cap that facilitates syringe plunging. Specifically designed for sealing glass vials and bottles, the center disc tears out to conveniently expose the top of the septa. These seals are bulk packed and manufactured by Science.
