Description
Standard filter paper, folded, 400 mm is a laboratory filtration medium with a basis weight of 64 g/m², supplied as pre-folded circles for convenient gravity filtration. Rated medium-fast, it supports routine solid–liquid separations where a practical balance of flow rate and particle retention is needed. The 400 mm diameter offers a generous working area for larger funnels and higher sample volumes in analytical, preparative, and teaching laboratories. Pre-folding eases placement in conical funnels and helps promote even wetting and steady flow during filtration. This standard-grade paper from manufacturer filtraTECH is suited to everyday clarification of solutions, collection of precipitates, and sample clean-up ahead of further processing. Packs of 100 pieces support efficient stock handling in busy lab environments. Typical uses include general qualitative work, preparation of filtrates, and handling of aqueous or organic mixtures under standard laboratory conditions. The medium-fast character makes the paper a dependable choice for workflows that require reliable throughput without specialised equipment, integrating smoothly into established funnel-based filtration protocols.

Questions about Folded filter paper for general use, 400 mm
What is this article?
Folded filter paper for general use, 400 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Filter paper, inside Filtration, in Consommables.
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.
