Description
Silicone seal GL 32 29 x 18 mm with PTFE collar is a laboratory sealing component made of silicone fitted with a vulcanised PTFE collar. It is intended for GL 32 threaded connections and measures 29 x 18 mm, covering a clamping range of 17,0 mm to 19,0 mm. Belonging to the septa category of laboratory accessories, the seal is supplied in packs of 10 pieces. The PTFE collar is vulcanised onto the silicone body, forming one integrated sealing element for the stated clamping range. Offered by manufacturer Witeg, each unit has a net weight of 0,004 kg. The 29 x 18 mm dimensions and 17,0–19,0 mm clamping range are specified for use with GL 32 fittings and matching tubing. Laboratory users choose this silicone–PTFE seal when a GL 32 seal with vulcanised PTFE sleeve is required for tubes in the 17,0 to 19,0 mm range. Construction details combine the silicone base with the vulcanised PTFE collar to match standard laboratory glassware and apparatus connections that employ the GL 32 thread standard.

Questions about Gaskets GL 32
What is this article?
Gaskets GL 32 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.
