Description
Round filter 240 mm is a circular laboratory filter disc with a filter diameter of 240 mm, designated grade (5) and characterised as slow and dense. This format is intended for filtration steps in which a slow flow rate and dense filter media are required for sample handling and separation work. Each pack contains 100 pieces, providing a practical stock quantity for routine bench use in research, teaching, and quality-control laboratories. The round filters from manufacturer Witeg suit standard assemblies and funnels that accept 240 mm discs and support everyday sample preparation and clarification tasks. Net weight of the pack is 0,422 kg, which is convenient for inventory and shared consumable stores. The generous 240 mm diameter offers ample surface area when larger aliquots or broader filter beds are needed. Slow, dense round filter paper of this type is a common choice wherever controlled gravity filtration is preferred over faster, more open grades. Supplied as a ready pack of 100 filters, the product integrates easily into laboratory replenishment workflows without unnecessary complexity.

Questions about Round filter 240mm
What is this article?
Round filter 240mm 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.
