Description
Qualitative filter paper in round format is designed for slow filtration of very fine precipitates in the laboratory. The cellulose paper has a low ash content of maximum 0,06 % and is intended for applications that demand tighter particle retention than medium-speed grades. With a grammage of 100 g/m², a pore size of 2–3 µm and a thickness of 200 µm, it provides fine retention and controlled flow comparable to Whatman grade 5. Supplied as 100 round filters of 70 mm diameter from manufacturer Labbox, the sheets suit smaller funnels and sample volumes typical of analytical and teaching workflows. Low residual ash helps minimise inorganic contribution when collecting or clarifying fine solids. The same slow-filtering quality is also offered as folded filters, so users can match format to apparatus while keeping one retention specification. Defined fine pores, higher grammage and consistent thickness make these round filters a dependable choice for qualitative work on fine precipitates, suspensions and other laboratory separations that benefit from slower, more retentive filtration.

Questions about Qualitative disc filter paper, slow flow rate, Ø70 mm, 100 pcs
What is this article?
Qualitative disc filter paper, slow flow rate, Ø70 mm, 100 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Filter paper, inside Filtration, in Lab consumables.
Filter paper is a cellulose sheet of a stated retention and speed. Qualitative paper clarifies. Quantitative, ashless paper is for a precipitate that will be weighed or ashed, because the paper itself leaves almost no ash. The diameter has to match the funnel.
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.
