Description
Quantitative hardened folded filter paper with medium-fast filtration is intended for non-critical quantitative laboratory work. Made from cellulose with a low ash content of maximum 0,02 %, it offers a practical compromise between ash-free quantitative grades (maximum 0,002 %) and qualitative low-ash papers (maximum 0,06 %). Medium filtration speed balances flow rate and particle retention for everyday analytical use. The sheet has a grammage of 80 g/m², a pore size of 8–12 µm and a thickness of 270 µm, and is highly moisture-resistant. This pack contains 100 pre-folded filters of 125 mm diameter, supplied in a box for convenient funnel loading. Equivalent to Whatman 52, the grade from manufacturer Labbox supports routine gravimetric work, sample clarification and general filtration where moderate residual ash is acceptable. The pre-pleated format promotes consistent wetting and steady flow during preparation and analysis.
This article belongs on Filter paper, in Filtration.

Questions about Hardened Quantitative folded filter paper, medium flow rate, Ø125 mm, 100 pcs
What is this article?
Hardened Quantitative folded filter paper, medium flow rate, Ø125 mm, 100 pcs 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.
