Description
Gasket silicone/PTFE is a laboratory sealing gasket for GL 25 threaded bottle and vessel connections, with an outer diameter of 23,5 mm. The silicone/PTFE construction is intended for use as a seal between screw caps and container necks in everyday laboratory glassware and plastic labware. It supports secure closure of bottles, vessels and related containers where a flexible gasket is required at the thread interface. Packaged as 25 pc(s) with a pack weight of 0,101 kg, the set suits laboratories that stock spare seals for multiple GL 25 systems. These gaskets from manufacturer Bohlender belong to the seals, hose connectors and accessories range used with laboratory containers, bottles, tins and canisters. They are practical consumables for analytical, preparative and general lab workflows that rely on GL screw threads. The components can be fitted as replacement seals during routine maintenance of bottle closures without specialised tools. Clear sizing to GL 25 and 23,5 mm diameter helps match existing caps and necks in standardised labware setups.
This article is part of Bottle accessories (pouring rings, dispensers, caps), in Bottles & containers.

Questions about Gasket silicone/PTFE, GL 25, Ø 23.5 mm, 25 unit(s)
What is this article?
Gasket silicone/PTFE, GL 25, Ø 23.5 mm, 25 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.
