Beschrijving
Qualitative filter paper, 125 mm is a circular laboratory filtration medium for routine qualitative separations. With a basis weight of 80 g/m² and a very fast filtration rate, the sheets support efficient liquid throughput when clarifying solutions or isolating coarser precipitates under gravity filtration. The 125 mm diameter fits common funnels and filtration assemblies used in teaching, quality-control and research laboratories. Packaged as 100 pieces from manufacturer filtraTECH, the paper is intended for everyday qualitative work where consistent sheet size and rapid flow are required. Its light grammage and open character help liquids pass quickly while retaining solid material during standard sample preparation. Laboratories can deploy these discs for solution clarification, solid–liquid separation and preparatory steps ahead of further analytical work. Uniform diameter and basis weight support repeatable filtration practice across multiple runs without specialised equipment. The format integrates smoothly into general laboratory material workflows for qualitative filtration tasks.

Questions about Qualitative filter paper, 125 mm
What is this article?
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 Verbruiksartikelen.
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.
