Description
Qualitative folded filter paper, 125 mm is a laboratory filter medium for everyday qualitative solid–liquid separations. With a basis weight of 80 g/m² and a very fast filtration rating, it supports rapid clarification of suspensions and recovery of precipitates where quantitative residue analysis is not required. The pre-folded 125 mm circles match widely used funnel sizes and present a larger working surface than flat sheets, which can shorten preparation time at the bench. Each unit supplies 100 pieces for continuous use in teaching, research and industrial quality-control settings. Offered by manufacturer filtraTECH, this qualitative grade is intended for general wet chemistry, sample clean-up and routine filtration rather than ashless or high-purity applications. Moderate sheet weight helps maintain handling strength when wet, while the very fast flow characteristic suits procedures that prioritise throughput. Laboratories in chemistry, environmental testing and life sciences can deploy these folded circles wherever consistent, ready-to-use qualitative filter paper is needed.

Questions about Folded qualitative filter paper, 125 mm
What is this article?
Folded qualitative filter paper, 125 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.
