Description
Silicone seal GL45 42x32 with PTFE collar is a precision laboratory seal for GL 45 connections that require a larger inner bore. It features a silicone body with a vulcanised PTFE collar, combining resilient sealing force with a chemically resistant contact surface. Outer diameter measures 42 mm and inner diameter 32 mm, intended for tubes of 31,0–33,0 mm. This configuration is well suited to bottle necks, transfer lines and vessel ports in chemical, pharmaceutical and life-science laboratories. The pack contains 10 pieces for convenient stock and replacement. Manufactured by Witeg, the seal supports dependable closure where both mechanical fit and material compatibility matter. Net weight is 0,006 kg per piece. Use it wherever GL 45 threading and the stated tube diameter range must be matched precisely, ensuring a stable, low-leak interface without compromising the inertness of the PTFE face against process media.

Questions about Gaskets GL 45
What is this article?
Gaskets GL 45 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.
