Beschrijving
Allihn filter tube, 30 ml, Por. 3 is a borosilicate 3.3 glass filtration tube fitted with a VitraPOR® sintered filter plate of 20 mm diameter and porosity grade 3. The working height above the filter plate measures 100 mm, providing adequate capacity for reduced-pressure Allihn-style filtrations. Designed for qualitative analysis and preparative chemistry, the tube enables efficient solid–liquid separations under vacuum. The chemically resistant borosilicate 3.3 glass body withstands typical laboratory solvents and thermal stress encountered in routine filtration workflows. Supplied by manufacturer ROBU - Stereon, this Allihn filter tube is intended for laboratories performing preparative work and analytical sample clean-up. The integrated fritted disc of defined porosity ensures reproducible retention characteristics while the cylindrical geometry above the plate accommodates moderate sample volumes. Packaged as a practical multi-piece unit, the filter tubes are ready for immediate use in vacuum filtration assemblies.
This article belongs on Sintered glass filter plates & discs, in Filtration.

Questions about Filter Tube Allihn, 30 ml, Por. 3
What is this article?
Filter Tube Allihn, 30 ml, Por. 3 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.
