Description
Filter paper 400 is a medium-fast clarifying grade provided as a round filter with a 250 mm diameter and a basis weight of 61 g/m². It is suited to laboratory clarification workflows that call for moderate filtration speed and effective particle retention during routine sample clean-up. The 250 mm circular format matches larger funnels and holders and is convenient when greater filter area is preferred for clarifying steps. Delivered as 100 pieces per pack, the presentation supports repeated runs and straightforward stock management in busy laboratories. Grade 400 paper from manufacturer Hahnemühle is intended for clarifying applications, helping clear liquids of suspended solids ahead of further analysis or processing. Medium-fast characteristics give a workable compromise between throughput and retention for general laboratory use. The round 250 mm geometry simplifies placement and handling in standard filtration setups. Consistent basis weight supports predictable behaviour from disc to disc. This filter paper integrates into common wet-chemistry, quality-control, and teaching protocols where clarifying filtration is an established preparatory stage.

Questions about Filter paper 400, for clarification ,medium fast, 61 g/sqm ,Discs 250 mm
What is this article?
Filter paper 400, for clarification ,medium fast, 61 g/sqm ,Discs 250 mm is the article on this page. Luminix Health distributes Hahnemühle 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.
