Description
Qualitative filter paper, folded, 190 mm is a pre-folded laboratory filtration medium for routine qualitative work. Specified at 150 g/m² with medium/slow filtration behaviour, it provides controlled flow suited to everyday sample clarification and precipitate handling. The folded format seats readily in conical funnels and reduces preparation time compared with flat sheets that must be creased by hand. A diameter of 190 mm matches larger common laboratory funnels used in teaching labs, QC benches and research workflows. Each pack contains 100 pieces, giving a practical stock level for repeated filtration steps. This folded qualitative filter paper from manufacturer filtraTECH is offered in the familiar 150 g/m² medium/slow grade for separations that do not require quantitative ash-free papers. Medium/slow performance supports procedures where retention and manageable throughput matter more than ultra-fast flow. Ready-folded discs can be taken straight from the pack and placed into standard filtration apparatus for consistent day-to-day laboratory use.

Questions about Folded qualitative filter paper, 190 mm
What is this article?
Folded qualitative filter paper, 190 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.
