Description
Silicone seals GL 32 with an outer diameter of 29 mm and an inner diameter of 16 mm are laboratory sealing components for GL-threaded connections and tubing in the 15,0–17,0 mm range. Manufactured from silicone without a PTFE cuff, they present a soft, resilient sealing face that seats reliably against glass, metal and polymer fittings used in analytical and preparative work. The 29 mm outer diameter corresponds to standard GL 32 screw caps and adapters, while the 16 mm bore is intended for larger-diameter process or transfer tubes. These seals support leak-tight joints on reagent vessels, reaction systems and media lines where a pure silicone contact surface is required. Offered in packs of 10 pieces from manufacturer Witeg, they are convenient consumables for chemistry, life-science and quality-control laboratories. Their compact geometry and low unit mass facilitate easy stocking and rapid replacement during maintenance cycles. Well suited to septa and general sealing duties on GL 32 hardware, the seals provide a straightforward, chemically resistant interface without additional sleeve materials, helping ensure dependable connections throughout routine laboratory operations.

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