Description
Filter funnel, 50 ml, Por. 2 is a laboratory filtration funnel manufactured from borosilicate 3.3 glass and fitted with a VitraPOR® sintered filter plate of 36 mm diameter at porosity grade 2. The height above the filter plate reaches 53 mm, giving a practical working volume for the nominal 50 ml capacity during vacuum or gravity filtration. This design supports efficient solid-liquid separations of precipitates, crystals and particulate matter in chemical synthesis, analytical chemistry and quality-control workflows. The integrated fritted disc provides uniform medium porosity for reproducible flow rates without the need for separate filter papers in many standard protocols. Supplied as a single unit from manufacturer ROBU - Stereon, the funnel benefits from the well-known thermal shock resistance and chemical durability of borosilicate 3.3, allowing repeated use with common laboratory solvents and reagents. Its compact form factor suits benchtop filtration setups while maintaining sample integrity and minimizing hold-up volume. Ideal for routine preparative and analytical tasks that require reliable particle retention at porosity 2.
This article belongs on Sintered glass filter plates & discs, in Filtration.

Questions about Filter Funnel, 50 ml, Por. 2
What is this article?
Filter Funnel, 50 ml, 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 Consommables.
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.
