Description
Gas washing bottle head FK 9 mm Por. 3 is a laboratory glassware component made of borosilicate 3.3 for gas washing bottle assemblies. It incorporates a VitraPOR® filter candle of 9 mm diameter with porosity 3 and is designed to fit bottle types 42 09* or 42 13*. This head enables controlled introduction and dispersion of gases into washing liquids during scrubbing, purification or humidification procedures common in analytical chemistry and process laboratories. The borosilicate 3.3 construction provides the chemical and thermal characteristics required for repeated laboratory use with a wide range of reagents. Offered as a single piece, the accessory from manufacturer ROBU - Stereon integrates directly into compatible gas washing systems without additional adapters. Porosity grade 3 defines the frit structure of the filter candle, supporting consistent bubble formation and gas-liquid contact. Suitable for modular setups in research, quality control and teaching laboratories, the head maintains optical clarity and dimensional stability under typical operating conditions. Its straightforward design facilitates cleaning and reassembly between experiments while preserving the integrity of the gas path through the fritted element.

Questions about Washing Bottle head, FC 9 mm Por. 3
What is this article?
Washing Bottle head, FC 9 mm Por. 3 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.
