Description
Silicone rubber septa for GL 25 closures are larger sealing discs intended for laboratory bottles, vessels and related consumable systems. Each septum has a diameter of 22 mm and a thickness of 2 mm, corresponding to common GL 25 screw-cap dimensions used with seals, hose connectors and accessory fittings. The silicone rubber body provides a flexible, compressible barrier for sampling access or temporary sealing of wider-neck laboratory containers. Available as a pack of 10 pieces with a unit weight of 0,001 kg, the format suits controlled restocking where fewer, larger septa are required per order. They form part of the labware assortment for containers, bottles, tins and canisters and their sealing accessories. Produced by DWK Life Sciences, the product is defined by material, GL 25 fit, 22 mm diameter and 2 mm thickness only, without further purity or sterility claims. Select these septa when GL 25 silicone discs of 22 mm diameter and 2 mm thickness are specified for standard laboratory sealing and access applications.
This article is part of Polymers, PEGs & silicones, in Organic chemicals & synthesis reagents.

Questions about Septa, made of silicone rubber, GL 25, Ø 22 mm, thickness 2 mm, 10 unit(s)
What is this article?
Septa, made of silicone rubber, GL 25, Ø 22 mm, thickness 2 mm, 10 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.
