Beschrijving
Standard filter paper, folded, 190 mm is a laboratory cellulose filter medium for routine qualitative separations and larger-volume clarification work. With a basis weight of 73 g/m² and a fast flow rate, these pre-folded circles support efficient gravity filtration of precipitates and suspended solids in analytical, teaching and quality-control laboratories. The 190 mm diameter fits larger funnel sizes commonly used when higher throughput or bigger sample volumes are required. Each unit is packed as 100 pieces, providing a practical stock level for busy benches and shared facilities. The folded construction shortens preparation time and helps the sheet seat cleanly in the funnel cone for uniform filtration. Manufactured by filtraTECH, this standard grade delivers the reliable handling and wet performance associated with everyday laboratory filter papers for aqueous systems and many compatible organic solvents where rapid filtration is preferred. Applications include clarifying solutions, collecting coarse precipitates, rinsing solids and preparing samples ahead of further analytical or drying steps with standard laboratory glassware.

Questions about Folded filter paper for general use, 190 mm
What is this article?
Folded filter paper for general use, 190 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Filter paper, inside Filtration, in Verbruiksartikelen.
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.
