Description
Qualitative filter paper, round, general purpose, medium-fast filtering is cellulose filter paper for routine laboratory work. It offers a pore size of 7–10 µm, a grammage of 65 g/m² and a thickness of 170 µm, giving medium-fast flow suited to everyday qualitative separations. Maximum ash content is 0,10 %. Each unit supplies 100 round filters of 240 mm diameter in plastic packaging without a box. This parchment-style paper for general laboratory use, from manufacturer Labbox, is described as equivalent to Whatman 93. The retention range and filtration speed support clarification of suspensions, collection of precipitates and similar qualitative steps in research, teaching and quality-control settings. Consistent sheet properties aid reproducible handling on standard funnels, while the cellulose construction provides reliable wet strength for typical bench filtration workflows where medium-fast performance is required.

Questions about Qualitative disc filter paper for general use, medium flow rate, Ø240 mm, 100 pc
What is this article?
Qualitative disc filter paper for general use, medium flow rate, Ø240 mm, 100 pc is the article on this page. Luminix Health distributes Labbox 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.
