Description
Qualitative technical papers, smooth Grade 4 b, provide filter media for analytical and technical laboratory use. The smooth Grade 4 b surface is suited to routine qualitative filtration, sample preparation support, and general technical paper applications at the bench. Packs contain 100 pieces, offering a convenient working quantity for continuous laboratory demand. With a net weight of 0,072 kg and a gross weight of 0,118 kg, the pack is straightforward to handle, store, and distribute within shared laboratory spaces. This paper type from manufacturer Sartorius is described as suitable for analytical and technical purposes, covering filtration sheets as well as protective underlays and work-surface covering. Laboratories employ such qualitative-technical grades for clarification steps, qualitative separations, and bench protection where a smooth finish is advantageous. Produced in Germany, these papers integrate easily into standard analytical and technical workflows that rely on dependable cellulose filter media. Grade 4 b smooth papers remain a practical choice when consistent technical performance is needed without moving to specialised quantitative filter grades.

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.
