Description
Round filter yellow band (3) is a qualitative laboratory filter paper designed for medium-fast solid–liquid separation in everyday analytical and preparative workflows. The yellow-band (3) grade provides a balanced filtration rate suitable for clarifying suspensions and collecting precipitates without the slower throughput of finer grades. Specified as low-fat, the paper is appropriate where minimal residual fat is preferred during sample work-up. Each disc measures 125 mm in diameter, fitting standard laboratory funnels and filtration setups used across chemical, environmental, and life-science laboratories. The pack contains 100 pieces, supporting continuous bench use and convenient restocking of shared filtration points. Net weight is given as 0,137 kg per pack. These filters are intended for gravity filtration and routine vacuum-assisted steps with aqueous and many common organic media under normal laboratory conditions. From manufacturer Witeg, the 125 mm yellow-band round filter helps standardise sample preparation, clarification, and precipitate recovery ahead of further analysis or processing, with consistent size and grade supporting reproducible day-to-day performance.

Questions about Round filter 125mm
What is this article?
Round filter 125mm 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.
