Description
Screw closure for narrow-neck bottle 500 ml is a laboratory screw cap with GL 25 thread for matching Enghals (narrow-neck) bottles of 500 ml capacity. Fabricated from PE-LD in a natural colour, it offers a practical seal for everyday laboratory storage, handling and transport of liquids and reagents in compatible containers. The GL 25 thread supports secure engagement with the corresponding narrow-neck bottle finish, aiding sample work, media holding and general bottle closure tasks. This PE-LD screw closure from manufacturer Witeg comes as a single piece and suits laboratories needing replacement caps or extra closures for PE-LD narrow-neck bottle systems. Natural-coloured low-density polyethylene keeps the cap light and convenient for general lab use where PE-LD performance is suitable. Apply it to reseal 500 ml narrow-neck bottles after dispensing, sampling or preparation, helping keep bottle sets organised on the bench and in storage areas. The focus remains on straightforward screw-on function for standard laboratory bottle workflows that call for GL 25 closures on 500 ml narrow-neck formats.

Questions about Closure narrow neck bottle 500ml
What is this article?

A laboratory glass bottle is borosilicate or soda-lime, with a stated capacity and a neck for a screw cap or a ground stopper. Glass is the choice when the liquid attacks a plastic, or when the bottle will be heated or autoclaved.
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.
