Description
Gas washing bottle base, 250 ml, NSK 45/40 is the lower section of a laboratory gas washing bottle fabricated from borosilicate glass 3.3. The component features a standard ground joint NSK 45/40 that ensures a reliable, gas-tight connection to matching upper parts and accessories. With a nominal capacity of 250 ml it is well suited for gas scrubbing, purification and absorption procedures in analytical and preparative chemistry. The chemically resistant borosilicate 3.3 construction withstands thermal stress and aggressive media commonly encountered in gas-washing applications. This base is designed to fit the corresponding upper sections 34 10* and 34 25*, allowing flexible assembly of complete washing bottles according to experimental needs. Supplied as a single piece from manufacturer ROBU - Stereon, the item integrates smoothly into existing laboratory glassware sets. Its robust design supports repeated use under typical laboratory conditions while maintaining dimensional accuracy of the joint. Ideal for research, quality-control and teaching laboratories that require modular gas-washing equipment.

Questions about Washing Bottle lower part, 250 ml, ST 45/40 cone
What is this article?
Washing Bottle lower part, 250 ml, ST 45/40 cone is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Wash bottles, inside Bottles & containers, in Labware.
A wash bottle is a squeeze bottle with a bent delivery tube, used to rinse a precipitate or a electrode with a small directed stream. The liquid inside is usually water or a solvent, and the bottle has to tolerate that liquid.
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.
