Description
Round filter 125 mm blue band (5) is a slow, dense laboratory filter paper intended for fine particulate retention and clear filtrates. The circular sheets have a filter diameter of 125 mm and follow the established blue-band grading for careful, low-speed filtration work. Supplied in packs of 100 pieces, the format suits routine sample preparation, qualitative analysis, and general wet-chemistry workflows where a tight paper grade is preferred. These round filters from manufacturer Witeg are straightforward to load into funnels and holders matching the stated diameter, supporting consistent handling across batches. The dense structure supports applications that prioritise clarity over speed, while the standardised blue-band designation helps laboratories keep filtration grades organised. Net weight per pack is 0,115 kg. Use them wherever a reliable slow blue-band round filter of 125 mm is specified for everyday laboratory filtration tasks.
This article is part of Filter paper, in Filtration.

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.
