Description
Qualitative filter paper, 55 mm is a medium laboratory filter paper with a basis weight of 87 g/m², intended for routine qualitative filtration in analytical, teaching, and research laboratories. The circular 55 mm discs are sized for common small funnels and filtration holders used when clarifying liquids, collecting precipitates, or preparing samples ahead of further testing. Medium filtration behaviour offers a practical balance between particle retention and flow rate, supporting everyday gravity filtration without specialised equipment. Each pack contains 100 pieces, giving a convenient stock level for continuous bench work and shared laboratory stations. This qualitative grade from manufacturer filtraTECH is suited to general chemistry, life-science, and quality-control workflows where quantitative ash or gravimetric precision is not required. The 87 g/m² sheet weight aids wet handling stability while remaining compatible with standard aqueous and many organic solvent procedures. Use these 55 mm medium qualitative papers for consistent day-to-day separations, solution clean-up, and sample conditioning across typical laboratory protocols that rely on reliable, straightforward filter media.

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 Consommables.
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.
