Description
Silicone rubber septa sized for GL 18 threads deliver elastic disc seals for laboratory bottles, vessels and accessory closures. Each piece has a diameter of 16 mm and a thickness of 2 mm, aligning with typical GL 18 cap formats used across seals, hose connectors and related labware. The silicone rubber material offers a soft, compressible interface suitable for sampling, transfer or temporary closure tasks where a replaceable septum is preferred. Supplied in packs of 20 pieces at a unit weight of 0,001 kg, they support efficient replenishment of consumable stocks in research and quality-control environments. These components sit in the laboratory glass, vessels and consumables range covering containers, bottles and sealing accessories. From manufacturer DWK Life Sciences, the specification is limited to silicone rubber construction, GL 18 compatibility, 16 mm diameter and 2 mm thickness—no extra performance grades are stated. Choose this format when protocols call for GL 18 silicone septa with a 16 mm disc and 2 mm profile for everyday laboratory sealing work.
This article belongs on Polymers, PEGs & silicones, in Organic chemicals & synthesis reagents.

Questions about Septa, made of silicone rubber, GL 18, Ø 16 mm, thickness 2 mm, 20 unit(s)
What is this article?
Septa, made of silicone rubber, GL 18, Ø 16 mm, thickness 2 mm, 20 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Polymers, PEGs & silicones, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A polymer, a PEG or a silicone is sold by molecular weight, or by viscosity, as much as by name. PEG 400 and PEG 4000 are different liquids and solids. A silicone oil's viscosity grades are the product range. The average molecular weight is the specification.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
