Description
Qualitative technical papers, smooth, Grade 3 hw are filter papers suited to analytical and technical purposes. The smooth Grade 3 hw format provides a practical cellulose medium for general laboratory filtration tasks where qualitative separation or technical clarification is required rather than strict quantitative ash-free work. Supplied as a pack of 100 pieces with a net weight of 0,065 kg and a gross weight of 0,100 kg, the papers originate from Germany (Niedersachsen) and are stored at room temperature. In day-to-day laboratory use they support sample preparation, routine analytical filtration, and technical process steps that call for a reliable smooth paper grade. The designation qualitative-technical reflects their dual suitability for analytical bench work and broader technical applications. Manufactured by Sartorius, Grade 3 hw smooth papers integrate into standard filtration assemblies used across research, teaching, and industrial quality-control environments. Their straightforward specification makes them a convenient choice whenever a smooth qualitative technical paper is specified for non-gravimetric filtration duties.

Questions about Technical papers, smooth/ Grade 3 hw
What is this article?
Technical papers, smooth/ Grade 3 hw is the article on this page. Luminix Health distributes Sartorius 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.
