Description
Qualitative filter paper, 55 mm is a circular laboratory filtration medium for routine qualitative separations. It has a basis weight of 80 g/m² and a very fast filtration rate, supporting efficient clarification and particle retention in everyday analytical and teaching workflows. The 55 mm diameter fits smaller funnels and compact filtration setups used for sample preparation and general laboratory work. Packs contain 100 pieces, so benches can stay stocked for continuous use. This qualitative grade from manufacturer filtraTECH is intended where rapid throughput is the priority rather than quantitative ash or retention grading. The light basis weight promotes quick flow while remaining practical for day-to-day filtration in chemistry, biology, and quality-control environments. Laboratories that need consistent, ready-to-use qualitative discs will find the 55 mm size convenient for standard glassware. Each pack supplies very fast qualitative filter papers suited to routine procedures across typical lab material applications.
This article is part of Filter paper, in Filtration.

Questions about Qualitative filter paper, 55 mm
What is this article?
Qualitative filter paper, 55 mm is the article on this page. Luminix Health distributes filtraTECH 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.
