Beschrijving
Qualitative filter paper, folded, 70 mm is a pre-pleated laboratory filtration medium for routine qualitative work. With a basis weight of 80 g/m² and a very fast filtration speed, the folded format is ready to place in a funnel, reducing preparation time at the bench. The 70 mm diameter suits smaller funnels and compact set-ups used for clarifying solutions, collecting precipitates, or preparing samples before further analysis. Pack size is 100 pc(s), supporting teaching laboratories, quality-control stations, and research groups that perform frequent qualitative filtrations. This grade from manufacturer filtraTECH focuses on consistent sheet quality and rapid flow for general laboratory separations rather than quantitative ash determination. Pre-folding increases effective surface area in the cone and helps maintain open flow paths during solid–liquid separation. Typical uses include everyday aqueous filtrations, removal of coarse solids, and straightforward sample clean-up in preparative or educational workflows. Light basis weight together with very fast speed shortens cycle times while remaining simple to handle. Select this 70 mm folded qualitative paper when ready-to-use format and high flow are required in standard lab practice.

Questions about Folded qualitative filter paper, 70 mm
What is this article?
Folded qualitative filter paper, 70 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Filter paper, inside Filtration, in Verbruiksartikelen.
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.
