Description
Qualitative filter paper with a diameter of 55 mm provides a reliable medium for general laboratory filtration tasks. With a basis weight of 80 g/m² and a very slow filtration speed, the paper is well suited to applications that demand careful particle retention and clear filtrates rather than rapid throughput. Each circular disc measures 55 mm and is intended for gravity filtration, sample clarification and routine qualitative analysis across chemistry and life-science workflows. Supplied in a pack of 100 pieces, the format supports efficient stock management in busy laboratories and teaching environments. This qualitative filter paper from manufacturer filtraTECH is a practical choice for educational settings, quality-control benches and research groups performing standard separations where quantitative ash-free grades are unnecessary. The slow flow rate promotes thorough filtration of fine suspensions and precipitates under ambient laboratory conditions, helping users obtain well-defined filtrates for subsequent observation or simple testing procedures.
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.
