Description
Standard filter paper, 47 mm is a compact laboratory filtration medium with a basis weight of 73 g/m², supplied as plain discs for use in small funnels, holders, and related filtration setups. Rated medium, it is intended for routine solid–liquid separations where controlled flow and reliable particle retention are required. The 47 mm diameter matches common small-format laboratory hardware and is well suited to limited sample volumes in analytical, quality-control, and teaching environments. This standard-grade paper from manufacturer filtraTECH supports everyday tasks such as clarification of solutions, collection of fine precipitates, and preparation of samples before further analysis. Packs of 100 pieces allow convenient stock management for busy laboratories. Typical applications include general qualitative filtration, filtrate recovery, and handling of aqueous or organic mixtures under standard bench conditions. The medium filtration characteristic offers a balanced working profile for protocols that need consistent performance without specialised equipment, integrating readily into established small-scale filtration workflows across research and routine laboratory practice.

Questions about Filter paper for general use, 47 mm
What is this article?
Filter paper for general use, 47 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.
