Description
Round filter 55 mm is a circular laboratory filter disc with a filter diameter of 55 mm for routine filtration work. Manufacturer data specify grade (1) and a fast filtration character, making the medium suitable where relatively rapid flow through a round paper disc is required. Each unit is packed as 100 pieces, giving a convenient bench stock for repeated qualitative filtration steps in analytical, teaching and research laboratories. The format matches common funnel and holder sizes that accept 55 mm round filters, so the discs can be integrated into everyday sample preparation and separation workflows without special adaptation. Supplied from manufacturer Witeg, the product is described simply as a fast grade (1) round filter at Ø 55 mm in a 100-piece pack. Net weight is 0,026 kg per pack. These consumables support standard laboratory filtration practice whenever a defined disc diameter, fast grade designation and multi-piece pack quantity are the primary selection criteria for circular filter media.

Questions about Round filter 55mm
What is this article?
Round filter 55mm 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.
