Description
Allihn filter tube 30 ml P2 is a laboratory filtration glassware item with a 30 ml capacity, a fritted plate of porosity P2 and 20 mm diameter, and a stem diameter of 10 mm. The Allihn design supports gravity or vacuum filtration of solids from liquids in analytical and preparative work. Offered as a single piece with a net weight of 0,038 kg, the tube belongs to the Allihn filter tube range from manufacturer Witeg. Its defined plate and stem dimensions allow straightforward integration into standard laboratory assemblies. The P2 porosity grade is selected when finer retention characteristics are required for the intended separation. Compact 30 ml volume suits small-scale sample handling while maintaining the mechanical stability expected of laboratory glass filter tubes. Consistent geometry of the 20 mm plate and 10 mm stem promotes reproducible filtration behaviour across repeated uses. This model is intended for routine laboratory filtration tasks that specify a 30 ml Allihn tube with P2 porosity.

What is this article?
Filter tube, Allihn, 30 ml, P2 disc-dia is the article on this page. Luminix Health distributes Witeg 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.
