Description
Qualitative filter paper in round format with fast filtering behaviour is intended for laboratory filtration of coarse and gelatinous precipitates. The cotton-fibre cellulose sheets have a low ash content of maximum 0,06 %, a grammage of 95 g/m², a pore size of 20–25 µm and a thickness of 215 µm, supporting rapid throughput while retaining bulky solids. Each pack contains 100 round discs of 70 mm diameter, ready for use in standard funnels and filtration assemblies. Performance is positioned in the same class as Whatman 4 grade papers, making the discs suitable for routine qualitative work in teaching, quality-control and research laboratories. Supplied from manufacturer Labbox, the paper is offered in both round and folded formats within the same quality family. The cellulose material combines low residual ash with practical handling strength for everyday wet-chemistry separations. Pack net weight is 0,056 kg. These qualitative round filters provide a straightforward choice whenever coarse or gelatinous precipitates must be separated efficiently without requiring quantitative ashless grades.

Questions about Qualitative disc filter paper, fast flow rate, Ø70 mm, 100 pcs
What is this article?
Qualitative disc filter paper, fast 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.
