Description
Round filter black band 1 is a fast qualitative laboratory filter paper with a filter diameter of 185 mm, delivered in a pack of 100 pieces. This larger round format supports filtration of higher sample volumes or use in funnels that require a wide paper diameter, while the black band 1 grade provides the fast flow associated with that classification. Typical applications include clarification of suspensions, separation of coarse precipitates, and general preparatory filtration in analytical, industrial-lab, and teaching environments. Fast papers of this type help maintain throughput when the solid load would clog slower grades and when the finest particle retention is not essential. The 185 mm diameter should be matched to compatible funnels and holders so that the filter seats evenly and filtration proceeds uniformly across the surface. Filters from manufacturer Witeg are supplied as 100 pieces per pack for convenient stock on the bench or in the store. The straightforward round disc design remains easy to handle, fold, or place flat according to the chosen filtration setup, offering a practical paper option before any membrane-based steps.

Questions about Round filter 185mm
What is this article?
Round filter 185mm is the article on this page. Luminix Health distributes Witeg 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.
