Description
Gooch filter, 30 ml, porosity 5, NSK 29/32 is a precision laboratory filtration crucible manufactured from borosilicate glass 3.3. It incorporates a VitraPOR® sintered filter disc of 20 mm diameter with porosity grade 5 and is fitted with a standard ground joint NSK 29/32. The overall height of the unit is 90 ml, making it compact yet practical for routine analytical work. This Gooch-type filter is intended for gravimetric analysis, precipitate collection and washing steps where a defined pore size and chemical resistance are required. The borosilicate 3.3 construction provides good thermal shock resistance and high purity, while the integrated frit ensures reproducible filtration performance. Supplied in packs of 2 pieces from manufacturer ROBU - Stereon, the filter is suitable for use in classical wet-chemistry laboratories, teaching environments and quality-control settings. Its standardised joint allows direct connection to common laboratory glassware assemblies. The combination of defined porosity, robust glass quality and convenient joint size supports reliable sample preparation and quantitative recovery of solids.

What is this article?
Filter Funnel, Gooch, 30 ml, Por. 5, 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.
