Description
Qualitative filter paper, 320 mm, is a large-format circular filtration medium for qualitative laboratory work and sample clarification. With a basis weight of 80 g/m² and slow filtration behaviour, it supports careful gravity separations where particle retention and a clear filtrate are priorities. Packs of 100 pc(s) supply 320 mm discs that fit larger funnels and filtration set-ups used in preparative chemistry, environmental sample handling, teaching labs, and quality-control routines. The slow grade is appropriate for collecting finer precipitates, clarifying bulk solutions, and preparatory steps ahead of further analysis when quantitative ash-free paper is not required. This qualitative filter paper from manufacturer filtraTECH provides a straightforward circular format for everyday bench use: seat the disc in a suitable funnel, wet as needed, and run gravity filtration under normal laboratory conditions. Uniform basis weight and diameter help keep parallel filtrations consistent. Select the 320 mm qualitative slow grade when larger filter area and controlled flow are needed for routine qualitative separations and laboratory sample preparation.

Questions about Qualitative filter paper, 320 mm
What is this article?
Qualitative filter paper, 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.
