Description
Qualitative technical papers, smooth Grade 4 b, are laboratory sheets intended for analytical and technical purposes. Their smooth surface supports filtration-related handling as well as covering and protection duties on benches and worktops. Supplied in a pack of 100 pieces with a net weight of 2,263 kg, this format suits laboratories that need a ready stock of qualitative-technical paper for routine use. Grade 4 b is appropriate where a plain technical sheet is required for sample work-up support, temporary covering, or protective underlays during standard procedures. The paper comes from manufacturer Sartorius and originates in Germany, matching established laboratory practice in analytical chemistry, life sciences and technical settings. Application areas include filter papers, protective papers, benchcoat-style underlays, cover sheets and general work-surface protection whenever a smooth grade is preferred. Sheets are non-sterile and intended for general laboratory handling rather than sterile workflows. For everyday analytical support or as cover and protection paper, this smooth Grade 4 b quality offers a practical consumable for organised laboratory and technical work.

Questions about Technical papers, smooth/ Grade 4 b
What is this article?
Technical papers, smooth/ Grade 4 b 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.
