Beschrijving
Büchner funnel 4000 ml P4 is a glass filter nutsche for vacuum-assisted solid-liquid separation in the laboratory. It incorporates a sintered filter plate of porosity grade P4 with a plate diameter of 175 mm and an outer stem diameter of 30 mm, giving a usable volume of 4000 ml. The funnel is well suited to retaining finer particles during precipitate isolation, suspension clarification and solvent removal under reduced pressure. Supplied as a single unit weighing 2,468 kg net, it connects readily to standard filter flasks and vacuum lines used in analytical and preparative work. Porosity P4 is chosen when finer filtration is required while still permitting practical flow rates. Made by Witeg, the funnel belongs to a recognised family of glass filtration apparatus employed in chemistry, materials science and quality-control laboratories. Its robust dimensions and consistent plate geometry support reliable day-to-day filtration performance in research, process development and educational settings without the need for extra adapters.
