Description
Allihn filter tube 30 ml P3 is a laboratory glassware component designed for filtration tasks requiring a defined porosity grade. This filter tube features a P3 fritted plate with a diameter of 20 mm and a stem diameter of 10 mm, providing a practical working volume of 30 ml for sample preparation and separation work. The Allihn design supports efficient filtration of precipitates and particulates in routine analytical and preparative procedures. Supplied as a single unit with a net weight of 0,038 kg, the tube integrates readily into standard laboratory setups. Manufactured by Witeg, it offers reliable dimensional consistency for everyday use in chemistry and life-science laboratories. The combination of the 30 ml capacity, P3 porosity and compact stem geometry makes it suitable for gravity or vacuum-assisted filtration where moderate retention is required. Ideal for educational, research and quality-control environments that need durable, precisely specified filter tubes.

Questions about Filter tube, Allihn, 30 ml, P3 disc-dia
What is this article?
Filter tube, Allihn, 30 ml, P3 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.
