Description
Round filter papers with a diameter of 110 mm in black ribbon grade 1 are intended for rapid qualitative filtration in laboratory workflows. The fast filtration behaviour of this grade aids efficient removal of precipitates and particulate matter from solutions in analytical and preparative chemistry. Supplied as a pack of 100 pieces, the filters provide a convenient stock for routine gravity filtration. These circular papers from manufacturer Witeg fit standard laboratory funnels and support consistent handling across teaching, research, and quality-control applications. At 110 mm diameter they cover larger funnel sizes while retaining the familiar black ribbon grade 1 performance profile focused on speed. The round shape promotes even seating and steady flow during successive filtrations. Black ribbon grade 1 remains a standard selection when quick qualitative separation is preferred. These filters are well suited to general laboratory use wherever a fast 110 mm round filter paper is specified for day-to-day sample preparation and clarification tasks.
This article is part of Filter paper, in Filtration.

Questions about Round filter 110mm
What is this article?
Round filter 110mm 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.
