Description
Qualitative filter paper round filters with medium-fast filtration are pure cellulose discs sized for larger laboratory funnels and general analytical use. With a diameter of 240 mm, a pore size of 10–12 µm, a thickness of 200 µm and a grammage of 85 g/m², they offer a balanced retention-to-flow profile for routine qualitative separations. The paper is produced from pure cellulose and shows a low ash content of maximum 0,06 %, making it suitable for clarifying solutions, collecting precipitates and preparing samples in chemistry and life-science settings. Supplied in packs of 100 pieces from manufacturer Labbox, these round filters support standard gravity filtration where a larger working diameter is preferred. The grade is noted as equivalent to Whatman 1 and forms part of a range available as both round and folded formats, allowing laboratories to align on one medium-fast cellulose specification. Reliable sheet consistency aids handling and wet performance without special pretreatments, providing a versatile everyday filter medium for teaching, quality control and research benches.

Questions about Qualitative disc filter paper, medium flow rate, Ø240 mm, 100 pcs
What is this article?
Qualitative disc filter paper, medium flow rate, Ø240 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.
