Description
Qualitative filter paper, folded, 70 mm is a pre-folded medium-grade laboratory filter with a basis weight of 87 g/m² for rapid setup in small funnels and routine gravity filtration. The folded format reduces preparation time at the bench, helping maintain consistent fluting and contact with the funnel wall for efficient flow during qualitative separations. With a 70 mm diameter, the paper suits compact filtration assemblies used for clarifying small sample volumes, collecting precipitates, and preparing solutions ahead of further testing. Medium retention behaviour supports everyday wet-chemistry tasks in research, teaching, and quality-control environments where quantitative ash-free grades are not required. Each unit pack provides 100 pc(s), convenient for frequent use and shared laboratory inventory. This folded qualitative filter paper from manufacturer filtraTECH is intended for standard laboratory filtration workflows that benefit from ready-to-use folds, reliable medium-speed performance, and straightforward handling. It integrates smoothly into protocols for aqueous suspensions and common laboratory liquids.

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 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.
