Description
Silicone seal GL 25 22x10 mm is a precision laboratory sealing element intended for GL 25 screw-thread fittings. Made of silicone without a PTFE cuff, it offers an outer diameter of 22 mm and an inner diameter of 10 mm, accommodating tubing with outer diameters between 9,0 and 11,0 mm. The elastic silicone construction delivers a dependable, chemically resistant seal suitable for liquid and gas lines in everyday laboratory work. Supplied in packs of 10 pieces with a net weight of 0,002 kg per seal, the components from manufacturer Witeg integrate readily into chromatography systems, reaction apparatus and standard laboratory glassware. Their straightforward design permits rapid insertion into GL 25 caps, while the pure-silicone contact surface provides the flexibility and thermal stability expected of this elastomer. These seals support repeated use cycles and help maintain leak-free connections in research, analytical and quality-control environments that rely on consistent GL-thread accessories.

Questions about Gaskets GL 25
What is this article?
Gaskets GL 25 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.
