Questions about Nalgene™ Carboy Replacement Screw Closures and Gaskets
What is this article?
Nalgene™ Carboy Replacement Screw Closures and Gaskets is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Bidons & jerrycans, inside Bouteilles et contenants, in Matériel de laboratoire.
A canister or jerrycan holds litres, not millilitres, and it is shaped to be carried and to pour. The material has to survive the liquid for the whole time the can sits in the store.
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.
