Description
Gas washing bottle base 350 ml with porosity 2 and NSK 29/32 joint is a precision borosilicate 3.3 glass component intended for laboratory gas-washing and gas-scrubbing systems. The lower section contains a permanently fused VitraPOR® filter plate of porosity grade 2 that produces a coarser bubble pattern suited to higher gas-flow rates while still ensuring effective contact with the scrubbing liquid. The standardised NSK 29/32 ground joint guarantees a tight, interchangeable connection to matching tops and adapters. This base is designed to fit the corresponding 37 35* series upper parts, enabling quick assembly of complete gas-washing bottles for absorption, purification or humidification duties. Manufactured by ROBU - Stereon, the unit is supplied as a single non-sterile piece. Borosilicate 3.3 glass provides high chemical resistance and thermal durability under normal laboratory gas-handling conditions. The 350 ml capacity accommodates a broad spectrum of analytical and preparative workflows in chemistry, environmental monitoring and life-science laboratories. The porosity-2 frit balances efficient gas dispersion with reduced back-pressure, making the base particularly suitable for applications requiring moderate to elevated gas throughput.

What is this article?
Washing Bottle head , 350 ml, Por. 2, ST 29/32 cone 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.
