Description
O-ring DN 200 in silicone (VMQ) is a precision seal intended exclusively for desiccator bases fitted with a grooved flange. Its accurately matched profile creates a reliable airtight closure on desiccators equipped with a grooved ground joint, eliminating the need for joint grease during routine laboratory use. The silicone construction provides the flexibility and chemical resistance required for repeated opening and closing cycles while maintaining a consistent seal. Designed solely for the corresponding grooved-flange lower part, this O-ring ensures proper fit and performance when sized according to the nominal diameter (DN). Supplied as a single piece from manufacturer Duran/DWK Life Sciences, it supports clean, grease-free operation of laboratory desiccators. Ideal for applications demanding a tight, reusable seal without additional lubricants, the component integrates directly into compatible desiccator assemblies and contributes to contamination-free storage of moisture-sensitive materials.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about O-Ring, for Desiccator Base, with ring-grooved flange only, from silicone (VMQ)
What is this article?
O-Ring, for Desiccator Base, with ring-grooved flange only, from silicone (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.
