Description
Gasket silicone/PTFE is a laboratory sealing gasket for S 40 connections, with an outer diameter of 38 mm. The silicone/PTFE material combination is intended for sealing between closures and container necks on laboratory bottles and vessels that use the S 40 format. It supports secure fitting in glass and plastic labware used for handling and storing liquids and reagents. Delivered as 5 pc(s) with a pack weight of 0,031 kg, the gaskets are practical consumables for laboratories keeping spare seals for S 40 systems. These components from manufacturer Bohlender form part of the seals, hose connectors and accessories range associated with laboratory containers, bottles, tins and canisters. They fit analytical, preparative and general laboratory workflows that rely on standardised S 40 closures. Installation as a replacement gasket during routine maintenance of bottle caps and necks is simple and does not require specialised equipment. Clear S 40 designation and 38 mm diameter help ensure correct pairing with matching laboratory vessel openings and closures.

Questions about Gasket silicone/PTFE, S 40, Ø 38 mm, 5 unit(s)
What is this article?
Gasket silicone/PTFE, S 40, Ø 38 mm, 5 unit(s) is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Bottle accessories (pouring rings, dispensers, caps), inside Bottles & containers, in Labware.
Bottle accessories are the pieces on the neck: a pouring ring, a dispenser seat, a cap liner, a tamper ring. They decide how the bottle delivers and whether the closure still matches after the original cap is gone.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
