Description
Standard filter paper, 90 mm is a circular laboratory filtration medium designed for routine qualitative separation. It features a basis weight of 73 g/m² and a medium retention grade, providing a practical compromise between throughput and particle hold-up for general laboratory filtration. The 90 mm diameter accommodates larger funnels and higher sample volumes commonly encountered in analytical chemistry, preparative work, and teaching laboratories. Delivered as 100 pieces per pack, the discs supply a convenient format for continuous bench use. This standard grade paper from manufacturer filtraTECH is appropriate for clarifying liquids, collecting precipitates, and routine sample clean-up where membrane or hardened specialty papers are not required. Medium porosity supports typical filtration steps in research, quality-control, and educational environments that need reliable everyday filter paper at a larger diameter. The plain circular discs integrate with standard laboratory glassware and support steady handling across repeated filtrations in daily workflows.

Questions about Filter paper for general use, 90 mm
What is this article?
Filter paper for general use, 90 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.
