Stoppers Overview
Saint-Gobain rubber and silicone stoppers provide a secure seal to ensure container contents remain pure.

Folding Skirt StoppersFolding Skirt Stoppers

Two-part folding skirt stoppers are designed with a double seal to keep container contents secure. The lower section grips the outside of the container and the upper hollow plug features annular serrations to provide a tight seal at the rim. The stoppers are ideal for securing glass, metal and plastic containers. Upper hollow plug section can be perforated to extract contents without removing the stopper and remains watertight even after several perforations.

Injection StoppersInjection Stoppers

LabPure® Injection Stoppers are available in a variety of rubber as well as silicone compounds to ensure the best application compatibility. Each compound exhibits a low level of extractables to ensure sample purity. Available in 20mm size, they are ideal for maintaining sterility for a wide range of sample types.

Lyophilization (Freeze-Drying) StoppersLyophilization (Freeze-Drying) Stoppers

LabPure® Lyophilization Stoppers are produced from a chlorobutyl rubber compound to ensure the highest level of purity. Available in both 13mm and 20mm sizes they are ideal for most lyophilization applications. Both styles–Split Legs and Gillon provide better stability than the standard lyophilization stoppers during freeze-drying processes.
