Description
Bottle thread adapter GL45 to GL38 ETFE is a laboratory fitting that converts GL 45 bottle threads to the smaller GL 38 format. Constructed from chemically resistant ETFE, the adapter withstands exposure to many organic solvents, acids and bases used in everyday laboratory practice. It provides a secure mechanical interface for connecting larger reagent bottles to systems or closures designed for GL 38 necks, thereby improving flexibility in sample preparation, titration and storage applications. The lightweight component has a net weight of 0,020 kg and gross weight of 0,022 kg, together with a packaging volume of 0,001 m³. Offered as a single piece from manufacturer Eppendorf and originating in Germany, the adapter is suited to research, analytical and process-control laboratories that require reliable thread adaptation. Its durable ETFE body retains shape and sealing performance under normal laboratory temperatures and chemical loads. Installation is straightforward, allowing quick reconfiguration of bottle connections without specialised tools and supporting efficient workflow organisation on the bench.

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.
