Description
Round filter 185 mm yellow band (3) is a medium-fast laboratory filter paper for routine qualitative filtration where a balanced flow rate is required. Each disc has a filter diameter of 185 mm, matching common funnel sizes used in analytical and preparative work. The yellow band (3) grade denotes medium-fast filtration behaviour, while the low-fat paper character supports cleaner handling and reduces unwanted residue transfer during everyday laboratory use. Packs contain 100 pieces, giving a practical stock quantity for teaching labs, QC benches, and research groups that process multiple samples per day. These round filters from manufacturer Witeg are suited to clarifying solutions, collecting precipitates, and preparing samples ahead of further measurement or work-up. The larger filtration area helps process moderate volumes efficiently without changing hardware when the funnel geometry already fits 185 mm media. Consistent disc format simplifies loading and disposal in standard glass or plastic filtration setups across chemistry, life-science, and materials workflows.

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.
