Wheaton Closures

Unlined Aluminium Seals

Unlined Aluminum Seals are used in conjunction with stoppers to provide a secure closure for serum bottles and vials. Aluminum seals are available in a wide range of styles including open-top, center disc tear-out, and complete tear off. Choosing the correct aluminum seal involves determining the size needed. Seal diameters should correspond to the mouth OD of the chosen container. Serum bottles and vials typically have a 13 mm or 20 mm OD.
