Description
Standard filter paper, 70 mm is a laboratory filtration medium specified at 73 g/m² basis weight with fast filtration behaviour. The 70 mm diameter suits mid-size funnels and routine qualitative separations where quick throughput matters. Each unit supplies 100 pc(s), supporting continuous bench work in research, teaching, and quality-control laboratories. The 73 g/m² sheet weight offers a practical balance of handling strength and flow for folding, seating, and everyday clarification of solutions or removal of coarse solids. Fast filtration characteristics help reduce process time during sample preparation and general laboratory filtration steps. Available from manufacturer filtraTECH, this standard grade belongs to the laboratory materials range and is positioned for general rather than highly specialised analytical duties. A uniform 70 mm format eases stock control when several stations use the same funnel geometry. Teams seeking a clear, no-frills specification—grammage, speed class, and diameter—will find this paper a practical choice for day-to-day qualitative filtration workflows.

Questions about Filter paper for general use, 70 mm
What is this article?
Filter paper for general use, 70 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.
