Description
Crucible with filter plate, porosity 3, is a precision laboratory crucible made from high-quality borosilicate glass LBG 3.3. The vessel provides a 50 ml working volume and a diameter of 40 mm, and incorporates a built-in filter plate of porosity grade 3. Porosity 3 covers a pore-size range of 15–40 µm, which is appropriate for finer solid retention, analytical filtration and collection of precipitates during gravimetric or sample-preparation procedures.
This article is part of Sintered glass filter plates & discs, in Filtration.
The glass may be used up to a maximum temperature of 220 °C when both heating and cooling are performed slowly and in a controlled manner, reducing the risk of thermal shock. This single-piece unit from manufacturer Labbox belongs to the GLASSCO product type and is intended for everyday filtration and separation tasks in chemical, pharmaceutical and quality-control laboratories. Net weight is 0,052 kg. The combination of defined porosity, borosilicate durability and compact 50 ml format supports reproducible laboratory filtration under moderate thermal load.

What is this article?
Crucible with filter plate, porosity 3, cap. 50 ml , Ø 40 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.
