Description
Silicone seal GL32 29×10 with PTFE collar is a laboratory sealing component for GL 32 screw-thread connections. Manufactured from silicone with a vulcanized PTFE collar, it combines the elasticity of silicone with the chemical resistance of PTFE at the media-contact surface. The seal has an outer diameter of 29 mm and an inner diameter of 10 mm, and is intended for tubing with outer diameters from 9,0 to 11,0 mm. These seals from manufacturer Witeg are supplied in packs of 10 pieces and are used wherever reliable sealing of GL 32 ports is required on laboratory glassware and apparatus. The vulcanized PTFE cuff helps shield the silicone body while maintaining a secure, conforming fit around the tube. Each piece has a net weight of approximately 0,005 kg. Suitable for chromatography setups, synthesis lines and general fluid handling, the component supports leak-tight connections on compatible systems. Material selection addresses both mechanical sealing performance and chemical durability in everyday laboratory practice with GL 32 fittings.

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.
