Description
Gas washing bottle head, NSH 34/35, porosity 0 is a borosilicate glass 3.3 accessory designed for gas scrubbing and purification assemblies in the laboratory. The head carries a standard ground joint NSH 34/35 and a frit of porosity 0, enabling controlled gas dispersion through the washing liquid. It is intended to fit matching gas washing bottle bodies designated 34 10* and 34 25*, forming a complete gas-washing unit when combined with the appropriate flask. Manufactured by ROBU - Stereon, the component is produced from chemically resistant borosilicate 3.3 glass, suitable for a wide range of aqueous and organic scrubbing media under normal laboratory conditions. Supplied as 1 pc, the head is ready for integration into existing gas-washing setups used for drying, humidifying or purifying gas streams. Porosity grade 0 provides a relatively coarse frit characteristic of this designation, supporting efficient bubble formation without excessive back-pressure. Typical applications include analytical gas preparation, inert-gas purification and process gas conditioning where a standardised NSH 34/35 joint and defined frit porosity are specified. The design focuses on interchangeability and chemical durability within gas washing bottle systems.

What is this article?
Washing Bottle head , ST 34/35 socket, Por. 0 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.
