Description
Silicone seal GL18 16x10 mm is a laboratory sealing component for GL 18 threaded connections. Manufactured from silicone without a PTFE cuff, it offers an outer diameter of 16 mm and an inner diameter of 10 mm and is designed for tubing with outer diameters from 9,0 to 11,0 mm. The flexible silicone construction provides a reliable seal on bottles, flasks and laboratory apparatus fittings in chemical and analytical environments. Available in packs of 10 pieces from manufacturer Witeg, these seals are well suited to septa and joint applications that demand elasticity and a secure fit. Their dimensions align with standard GL 18 glassware and connector systems, enabling leak-resistant tubing assembly within the specified diameter range. Appropriate for research, quality-control and preparative work involving GL-threaded closures and silicone sealing elements.

Questions about Gaskets GL 18
What is this article?
Gaskets GL 18 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.
