Description
Standard filter paper, 320 mm is a large-format circular laboratory filter medium for routine solid–liquid separation in analytical and preparative practice. It combines a basis weight of 73 g/m² with a fast filtration grade, enabling efficient flow during clarification of suspensions, recovery of precipitates, and preparation of samples for further testing. The 320 mm diameter is intended for correspondingly large funnels and filtration assemblies used when higher sample volumes are processed in chemistry, life-science, and quality-control environments. Packs of 100 pieces support continuous use in teaching labs, industrial QC benches, and research groups that rely on frequent gravity or simple vacuum filtration. This standard grade from manufacturer filtraTECH addresses everyday methods where rapid throughput is preferred to specialised retention specifications. Uniform sheet quality helps maintain predictable handling when discs are folded, seated, or trimmed. Common uses include aqueous sample work-up, general solids collection, and clarification steps before titration, spectroscopy, or storage. Choose 320 mm media when your apparatus is sized for this diameter and you need a consistent fast standard filter paper for regular laboratory filtration work.

Questions about Filter paper for general use, 320 mm
What is this article?
Filter paper for general use, 320 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.
