Allihn filter tube, 30 ml, Por. 4 is a borosilicate glass 3.3 laboratory filter tube designed for vacuum filtration according to the Allihn principle. It incorporates a VitraPOR® sintered filter disc of 20 mm diameter with porosity grade 4 and provides a working height of 100 mm above the filter plate. The 30 ml capacity makes the tube convenient for qualitative analysis and preparative chemistry applications where reduced-pressure filtration of moderate sample volumes is required. Constructed entirely from chemically resistant borosilicate 3.3, the filter tube withstands typical laboratory solvents and thermal stress encountered during routine filtration work. Available from manufacturer ROBU - Stereon, this Allihn-style tube supports efficient solid–liquid separations in analytical and synthetic laboratories. Supplied in packs of 5 pieces, it offers a practical consumable format for continuous laboratory use without compromising filtration performance or chemical compatibility.

Questions about Filter Tube Allihn, 30 ml, Por. 4
What is this article?
Filter Tube Allihn, 30 ml, Por. 4 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 Verbruiksartikelen.
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.
