Description
Round filter Ø 150 mm is a laboratory round filter designated grade (5), specified as slow and dense. With a filter diameter of 150 mm, it suits larger funnels and higher sample volumes where a controlled, slower filtration rate and dense media structure are required. The grade (5) slow, dense characterisation indicates a tighter filtration profile compared with fast, open grades, supporting work that prioritises retention behaviour over speed. Filters are packed as 100 pieces per pack, providing a convenient quantity for recurring analytical, preparative, or teaching workflows. These round filters from manufacturer Witeg arrive as plain circular filter media ready for immediate use in standard laboratory glassware. The 150 mm diameter offers a practical mid-to-large format for general solid–liquid separation, precipitate handling, and sample clarification steps. Uniform round cut helps reliable seating in funnels and reduces trimming. Country of origin is Great Britain. In summary, this article delivers grade (5) slow, dense round filters at 150 mm diameter in a 100-piece laboratory pack for everyday filtration tasks.
This article is part of Filter paper, in Filtration.

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.
