Description
Silicone rubber gasket GL60 is a PTFE-coated sealing element intended for laboratory glassware with GL 60 screw threads. Featuring a flexible silicone rubber body and a PTFE surface coating, it delivers chemical resistance and low adhesion while functioning as a septum or closure seal for larger bottles, flasks and reaction vessels. The gasket supports secure, inert connections in analytical chemistry, sample handling and general laboratory practice. Supplied as one piece with a net weight of 0,008 kg and originating from Germany, it is manufactured by Witeg. The PTFE coating reduces sample interaction and eases handling, whereas the silicone core preserves the elasticity needed for consistent performance over multiple opening and closing cycles. Compatible with standard GL 60 caps, this gasket is suited to research, quality-control and production laboratories requiring dependable septa for reliable glassware sealing.

Questions about Silicone rubber seal GL 60
What is this article?
Silicone rubber seal GL 60 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Bottle accessories (pouring rings, dispensers, caps), inside Bottles & containers, in Labware.
Bottle accessories are the pieces on the neck: a pouring ring, a dispenser seat, a cap liner, a tamper ring. They decide how the bottle delivers and whether the closure still matches after the original cap is gone.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
