Description
Standard filter paper, 70 mm is a qualitative laboratory filter paper intended for routine solid–liquid separation in analytical, teaching, and research workflows. It has a basis weight of 64 g/m² and medium-fast filtration behaviour, giving a practical balance between flow rate and particle retention for everyday wet-chemistry tasks. The 70 mm circular format fits common funnels and small Büchner assemblies used when clarifying solutions, collecting precipitates, or preparing samples ahead of further analysis. Packs contain 100 pieces, supporting continuous bench use without frequent reordering. Produced by filtraTECH, this standard grade offers consistent sheet thickness and handling strength when dry or wet, so discs fold cleanly and seat reliably in glassware. Medium-fast porosity suits general aqueous and many organic preparations where specialised ashless or hardened papers are not required. Laboratories in chemistry, life sciences, and quality control can deploy the media for teaching experiments, R&D screening, and production QC clean-up. Diameter, basis weight, and filtration speed align with conventional laboratory protocols, helping maintain reproducible filtration steps across repeated runs.

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 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.
