Description
Qualitative round filter paper for general purpose, medium-fast filtering, Ø 70 mm, is a cellulose laboratory disc intended for everyday filtration tasks. Maximum ash content is 0,10 %. The parchment-style paper has a grammage of 65 g/m², a pore size of 7–10 µm and a thickness of 170 µm, giving a balanced medium-fast flow suitable for routine clarification and general lab separations. Each pack contains 100 round filters in plastic packaging without an outer box, matching compact bench storage and high-throughput dispensing. The 70 mm diameter suits smaller funnels and standard qualitative setups. This grade is described as equivalent to Whatman 93 and is offered for general laboratory use rather than specialised quantitative work. Consistent pore range and basis weight support reproducible day-to-day filtration of suspensions and precipitates of moderate particle size. Available from manufacturer Labbox in the BRANCHIA PRAT DUMAS range, these round cellulose filters provide a practical medium-speed option for teaching, QC and research benches that need reliable qualitative paper in a simple round format.

Questions about Qualitative disc filter paper for general use, medium flow rate, Ø70 mm, 100 pcs
What is this article?
Qualitative disc filter paper for general use, medium 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.
