Description
Silicone seal (VMQ) is a GL 45 gasket measuring 26 x 42 x 5 mm for laboratory screw-connection systems. Made from silicone (VMQ), the seal provides a flexible, chemically suitable interface for GL 45 closures used with laboratory bottles and related glassware assemblies. The defined dimensions ensure a precise fit within the corresponding screw-connection geometry, supporting reliable sealing during liquid or gas handling operations. This single-piece replacement seal from manufacturer Duran/DWK Life Sciences is intended for maintenance and assembly of GL 45 laboratory setups where a durable silicone gasket is required. It is suitable for use in gas-washing and filtration arrangements that rely on screw-connection components, as well as general laboratory bottle systems needing a compatible VMQ seal. Compact net weight and standard laboratory material properties make it a practical spare part for routine laboratory workflows.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about Silicone Rubber Seals (VMQ)
What is this article?
Silicone Rubber Seals (VMQ) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
