Beschreibung
Allihn filter tube, 30 ml, Por. 2 is a borosilicate glass 3.3 filtration tube designed for vacuum-assisted Allihn filtration in qualitative analysis and preparative chemistry. It incorporates a VitraPOR® sintered filter disc of 20 mm diameter with porosity grade 2, providing reliable particle retention under reduced pressure. The working height above the filter plate measures 100 mm, giving adequate capacity for sample handling and solvent rinsing. Manufactured by ROBU - Stereon, the tube is intended for laboratory workflows that require controlled filtration of suspensions, precipitates or reaction mixtures. Borosilicate 3.3 glass ensures high chemical resistance and thermal stability during routine use. The Allihn configuration supports efficient solid–liquid separation when connected to a vacuum source, making the item suitable for analytical sample preparation, purification steps and general laboratory filtration tasks. Supplied as a practical multi-piece pack, the filter tubes are ready for immediate integration into existing glassware setups for both teaching and research laboratories.
This article belongs on Sintered glass filter plates & discs, in Filtration.

Questions about Filter Tube Allihn, 30 ml, Por. 2
What is this article?
Filter Tube Allihn, 30 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 Verbrauchsmaterialien.
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.
