Description
Round filter black band 1 is a fast qualitative laboratory filter paper with a filter diameter of 150 mm, supplied in packs of 100 pieces. It is suited to everyday filtration work where rapid flow is more important than ultra-fine retention, including clarification steps, removal of coarse solids, and preparatory filtration ahead of further analysis. The black band 1 designation identifies a fast grade commonly chosen for suspensions and precipitates that would otherwise slow medium or slow papers. At 150 mm diameter, the discs fit correspondingly sized funnels and filtration assemblies, giving a stable working area for larger sample volumes than smaller round formats. These filters from manufacturer Witeg are packed as 100 pieces, supporting continuous use in research, quality-control, and teaching laboratories that still rely on classical paper filtration. The round geometry is easy to centre and fold as required by the chosen funnel type. Select this size when your protocol or glassware calls for a 150 mm filter and a fast black-band performance profile without moving to membrane filters.

Questions about Round filter 150mm
What is this article?
Round filter 150mm 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.
