Description
Qualitative folded filter paper for general laboratory use enables very fast filtration of tough and viscous liquids. Made from long cotton fibres, this cellulose grade is very thick and durable, with a maximum ash content of 0,06 %. Specified at 130 g/m² grammage, 25–30 μm pore size and 430 μm thickness, it ranks among the fastest qualitative papers and maintains strength during handling of demanding samples. Each pack holds 100 pre-folded filters of 125 mm diameter from manufacturer Labbox, ready for funnel use in routine clarification and coarse separations. The same paper family is offered as plain round discs; the grade is positioned as equivalent to Whatman 114. The open pore structure supports high flow rates while retaining coarse or gelatinous precipitates, making these folded filters a convenient option for preparative workflows, teaching labs and quality-control applications that need reliable, rapid qualitative filtration with minimal preparation time.

Questions about Qualitative folded filter paper for general use, very fast flow rate, Ø125 mm, 1
What is this article?
Qualitative folded filter paper for general use, very fast flow rate, Ø125 mm, 1 is the article on this page. Luminix Health distributes Labbox 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.
