Description
Round filter Rotband (4) is a qualitative laboratory filter paper for medium to slow filtration applications. At 110 mm filter diameter, these circular sheets give ample surface area for clarifying larger sample volumes, collecting precipitates, and supporting general analytical workflows in research and quality-control settings. The Rotband (4) grade is selected when balanced particle retention and flow are needed, enabling separation of fine particulates from liquids within practical process times. Each pack holds 100 pieces, suitable for regular bench consumption; net weight is 0,104 kg per pack. These round filters from manufacturer Witeg match common funnel sizes and filtration assemblies used in chemistry, life-science sample preparation, and industrial testing laboratories. Consistent diameter supports repeatable handling during filtrate preparation, solution clarification, or precipitate recovery before further analysis. Specify this 110 mm medium-to-slow qualitative paper wherever standard laboratory filtration with a larger working diameter is required.
This article is part of Filter paper, in Filtration.

Questions about Round filter 110mm
What is this article?
Round filter 110mm 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.
