Description
Silicone rubber gasket GL14 is a PTFE-coated sealing element for laboratory glassware fitted with GL 14 screw threads. The combination of flexible silicone rubber and a PTFE surface coating provides a resilient seal that supports reliable closure of bottles, flasks and related vessels used in analytical and preparative work. Offered as a single piece with a net weight of 0,001 kg, this gasket is intended as a spare or replacement part for GL 14 connections where a chemically more inert contact face is preferred. The PTFE coating reduces adhesion at the sealing interface while the silicone body maintains elasticity under repeated assembly and disassembly. Suitable for use with corresponding screw caps and bottle necks, it belongs to the septa and sealing accessory category and is produced by manufacturer Witeg in Germany. Its defined GL 14 size ensures dimensional compatibility with standard laboratory thread systems, making it a practical component for maintaining leak-tight joints in routine laboratory handling of liquids and reagents without altering the original glassware geometry.
This article is part of Chromatography accessories, in Vials, caps & septa.

Questions about Silicone rubber seal GL 14
What is this article?
Silicone rubber seal GL 14 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Chromatography accessories, inside Vials, caps & septa, in Chromatography equipment.
These are the small chromatography parts that are not a column, a vial or a syringe: vial racks, solvent filters, waste caps, ferrule kits. A solvent inlet filter is what keeps the pump from swallowing particles out of the bottle.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
