Description
Filter funnel 125 ml, porosity 5 is a laboratory filtration funnel manufactured from borosilicate 3.3 glass and fitted with a VitraPOR® filter plate of 60 mm diameter. The height above the filter plate is 56 mm, giving a practical working volume for vacuum filtration of small to medium samples. Porosity grade 5 provides a finer frit structure suited to fine solid-liquid separations in analytical chemistry, sample preparation and general laboratory work. This Büchner-style nutsche funnel supports collection of fine precipitates, washing of solids and clarification of suspensions without always requiring additional filter paper. The chemically resistant borosilicate construction ensures durability under typical laboratory conditions. Supplied as a single piece from manufacturer ROBU - Stereon, the funnel combines reliable pore characteristics with straightforward handling on the bench. Its compact 125 ml capacity makes it convenient for routine research, quality-control and teaching applications where consistent fine filtration performance is required.

Questions about Filter Funnel, 125 ml, Por. 5
What is this article?
Filter Funnel, 125 ml, Por. 5 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.
