Description
Qualitative folded filter paper, 125 mm, is a laboratory filtration medium for routine qualitative separation and clarification tasks. With a basis weight of 88 g/m² and fast filtration behaviour, it allows efficient passage of liquid while retaining particulate matter on the paper surface. The filters arrive pre-folded, so they can be placed straight into a suitable funnel without additional preparation. Each pack holds 100 pieces, supporting continuous use in educational laboratories, quality-control stations, and general analytical environments. This qualitative paper from manufacturer filtraTECH is aimed at workflows focused on qualitative observation, sample clean-up, or preparatory filtration rather than quantitative residue determination. The 125 mm diameter suits mid-range funnel sizes and moderate sample volumes commonly encountered on the bench. Uniform basis weight and fold pattern help keep handling consistent across the pack. Teams that already use the same 88 g/m² fast qualitative line can choose 125 mm whenever funnel dimensions and throughput requirements make that diameter the practical match for gravity filtration steps.

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 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.
