Description
Filter funnel 75 ml, porosity 1 is a laboratory filtration funnel made from borosilicate glass 3.3 for efficient solid-liquid separation by vacuum or gravity filtration. It features an integrated VitraPOR® sintered filter plate measuring 48 mm in diameter with porosity grade 1, offering a medium pore size that balances retention of finer particles with practical flow rates. Above the filter disc the vessel rises 50 mm, providing a nominal capacity of 75 ml suitable for typical analytical and preparative sample volumes. Supplied by manufacturer ROBU - Stereon, this filter funnel supports everyday laboratory operations including precipitate collection, crystal isolation, suspension clarification and work-up of reaction mixtures in chemistry, life-science and materials research settings. The fused VitraPOR® plate removes the need for separate filter papers, simplifies assembly and helps maintain consistent filtration performance. Constructed entirely from durable borosilicate 3.3, the funnel exhibits good resistance to thermal shock and common laboratory chemicals, allowing straightforward cleaning and repeated use. Its compact 75 ml size integrates readily into standard vacuum filtration setups and is practical for parallel processing of multiple small batches in research, quality-control or teaching laboratories.

Questions about Filter Funnel, 75 ml, Por. 1
What is this article?
Filter Funnel, 75 ml, Por. 1 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.
