Standard filter paper, 70 mm is a circular laboratory filtration medium for routine qualitative separation tasks. With a basis weight of 73 g/m² and a medium retention grade, it offers a workable balance of flow rate and particle retention for general bench filtration. The 70 mm diameter matches widely used funnel sizes and mid-range sample volumes in analytical chemistry, life-science preparation, and teaching laboratories. Supplied in packs of 100 pieces, the discs form a practical consumable stock for ongoing laboratory work. This standard grade filter paper from manufacturer filtraTECH supports clarifying solutions, isolating precipitates, and preparing samples before downstream analysis when specialised membrane or hardened grades are unnecessary. Medium porosity suits everyday filtration across research, quality-control, and educational settings that require dependable day-to-day paper in a versatile diameter. The simple circular format fits standard glassware and promotes consistent handling during repeated filtrations in busy laboratory 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 Verbruiksartikelen.
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.
