Description
Silicone seal GL100 98x80 with PTFE collar is a laboratory sealing element designed for GL 100 threaded connections. It offers an outer diameter of 98 mm and an inner diameter of 80 mm, accommodating tubes in the 78,0 to 81,0 mm range. A vulcanised PTFE collar on the silicone body unites elastic sealing performance with the chemical inertness of PTFE at the wetted surface. This makes the seal suitable for bottles, reactors and process lines where reliable, chemically resistant joints are required. Delivered as a single piece with a net weight of 0,03 kg, it fits standard laboratory glassware and apparatus using GL 100 threads. The vulcanised silicone–PTFE construction resists separation during normal use and cleaning. Produced by manufacturer Witeg, the seal supports septa and general sealing applications in analytical and preparative laboratories. The PTFE collar helps minimise sticking and improves compatibility with many solvents and reagents, while the silicone core ensures a flexible, secure fit on larger GL connections.

Questions about Gasket GL 100
What is this article?
Gasket GL 100 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
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.
