Description
Crucible with filter plate, porosity 2, is a laboratory filter crucible with a nominal volume of 30 ml and an outer diameter of 35 mm. It is produced from high-quality borosilicate glass LBG 3.3 and incorporates an integral sintered filter plate with porosity grade 2, corresponding to a pore size range of 40–90 µm. This configuration supports solid–liquid separations, residue collection and gravimetric work where medium-fine retention is required. The glass body tolerates a maximum working temperature of 220 °C when heating and cooling are performed slowly and under control, helping to limit thermal stress on the filter disc and wall. Supplied as a single piece from manufacturer Labbox, the crucible suits routine analytical filtration, sample preparation and related laboratory workflows that benefit from a reusable glass filter vessel. Its compact 30 ml capacity and defined porosity make it practical for small- to medium-scale filtrations in research, quality-control and teaching laboratories. Net weight is 0,044 kg per unit. The design combines chemical resistance of borosilicate LBG 3.3 with a fixed filter plate so that filtration and subsequent handling can be carried out in one vessel without separate filter media.

What is this article?
Crucible with filter plate, porosity 2, cap. 30 ml , Ø 35 mm, 1 pc is the article on this page. Luminix Health distributes Labbox 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.
