Description
Filter paper 551 is a technical-grade round filter paper supplied as black discs with a basis weight of 95 g/m² and a diameter of 240 mm. Specified for slow filtration, this grade supports technical separation work where controlled flow is preferred for handling larger sample volumes or broader filter areas. The circular format is intended for laboratory funnels and holders sized for large-diameter round filters. Each unit is packed as 100 pc(s), offering a convenient stock quantity for laboratories that regularly use wide technical filter papers. The black surface enhances visual contrast when inspecting collected solids during qualitative technical filtration. With its 95 g/m² basis weight and slow filtration profile, grade 551 provides a consistent sheet for general laboratory and technical filtration tasks requiring a darker filter medium. These round filters from manufacturer Hahnemühle are non-sterile technical filter papers for everyday laboratory use. The 240 mm diameter addresses larger funnels and high-area filtration setups, while the uniform round cut aids straightforward placement and handling.

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.
