Description
Gas washing bottle head NSH 45/40, porosity 2 is a laboratory glassware component fabricated from borosilicate glass 3.3 for gas washing and scrubbing assemblies. It features a standard ground joint NSH 45/40 together with an integrated frit of porosity 2 that produces controlled gas dispersion when gases are bubbled through liquids. The head is matched to bottle bodies 34 10* and 34 25*, permitting modular use within established gas-washing bottle systems. Supplied as one piece, this accessory from manufacturer ROBU - Stereon offers the chemical durability and thermal shock resistance characteristic of borosilicate 3.3 glassware. Porosity grade 2 provides a defined bubble size and gas–liquid contact area suited to purification, humidification or reaction applications. The component is intended for everyday laboratory gas-handling tasks in research, analytical and preparative settings where consistent frit performance is essential. Its standardised joint guarantees secure, interchangeable connection to compatible vessels while preserving leak-tight integrity under normal laboratory conditions.

What is this article?
Washing Bottle head , ST 45/40 socket, Por. 2 is the article on this page. Luminix Health distributes ROBU - Stereon for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
