Description
DURAN® filtration attachment with glass rim is a borosilicate glass 3.3 filter component with a diameter of 90 mm and porosity 4, designed for reliable laboratory separation and purification. Filtration remains one of the most important separation techniques in the laboratory for isolating or purifying diverse media, and this attachment supports that workflow by allowing selection of size and porosity to match the application. The assembly comprises a receiving vessel, sealing ring, glass filter plate and funnel; it can be fully dismantled so that each individual part may be replaced or varied to adapt the filter to specific needs. Combined with three apparatus sizes and four porosity grades of filter plates, twelve distinct filtration configurations become available. Use of the glass filter plate can eliminate the need for filter paper or membrane in many cases. The glass rim is fire-polished and the white printed marking is permanently fused into the glass. Suitable for qualitative analysis, preparative chemistry and filtration without paper, this unit from manufacturer Duran/DWK Life Sciences delivers durable, reusable performance in routine laboratory filtration.

Questions about DURAN® Filter Disc, fused glass rim
What is this article?
DURAN® Filter Disc, fused glass rim is the article on this page. Luminix Health distributes DWK Life Sciences 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.
