Description
Qualitative filter paper, folded, 320 mm is a laboratory filtration medium for qualitative separations, clarification, and related wet-chemistry steps. It offers a basis weight of 88 g/m² and is specified as a fast grade, enabling efficient flow during gravity filtration of suspensions and precipitate-containing mixtures. Pre-folded sheets seat readily in funnels and help maintain a uniform cone shape, which supports reproducible handling when processing successive samples. The 320 mm diameter addresses larger funnel formats used in preparative work, teaching environments, and general laboratory practice. Supplied as 100 pc(s) per pack, the product suits stockrooms that need ready volume for routine filtration. These papers from manufacturer filtraTECH are aimed at qualitative tasks such as clarifying liquids, collecting visible solids, and generating filtrates for subsequent observation or measurement. Fast filtration behaviour, moderate basis weight, and the folded construction combine into a practical option for aqueous systems and many solvent-based workflows where speed and ease of use are priorities. Include this 320 mm qualitative folded filter paper in standard lab-material assortments for dependable day-to-day filtration alongside conventional funnels and receivers.

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