Description
Quantitative filter paper, 185 mm is a circular laboratory filtration medium specified for controlled, slow filtration work. It has a basis weight of 75 g/m² and carries the green-spot marking that identifies this slow filtration grade. Packs contain 100 pieces, each sheet cut to a 185 mm diameter so it fits larger analytical funnels and filtration assemblies used in routine wet chemistry. The slow flow characteristic supports careful retention of fine precipitates and suspended solids during gravity filtration, making the paper suitable for quantitative sample preparation and separation steps. Consistent sheet weight and diameter help laboratories maintain reproducible handling from batch to batch. This quantitative filter paper from manufacturer filtraTECH is intended for everyday use in research, teaching, quality-control and industrial laboratories where defined filtration speed and format matter. The green-spot coding allows quick visual identification on the bench, while the 75 g/m² basis weight provides a sturdy yet workable sheet for folding and seating in funnels. Choose the 185 mm size when matching larger funnel diameters and higher sample volumes in analytical workflows.

Questions about Quantitative filter paper, 185 mm
What is this article?
Quantitative filter paper, 185 mm is the article on this page. Luminix Health distributes filtraTECH 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.
