Our closures systems are manufactured from high-purity, biopharmaceutical-grade, platinum-cured silicone elastomers. These components and assemblies provide an aseptic seal for handling various highly sensitive fluids in biopharmaceutical applications.

The technology of these products ensure an unobstructed fluid path. Our closure systems allow you to easily retrofit your existing glass and plastic carboys, glass solution and media bottles, and stainless steel vessels for aseptic fluid transfer, sampling or sealing. One-piece construction eliminates product loss and contamination.
