Büchner funnel 4000 ml P2 is a laboratory glass filter nutsche designed for vacuum-assisted solid-liquid separations. It features a sintered glass filter plate of porosity grade P2 with a plate diameter of 175 mm and an outer stem diameter of 30 mm, providing a practical working volume of 4000 ml for medium-scale filtrations. The robust construction supports routine sample preparation, precipitate collection and solvent removal under reduced pressure in analytical and preparative workflows. Supplied as a single unit with a net weight of 2,478 kg, this funnel integrates easily into standard vacuum filtration assemblies used in chemistry, biochemistry and materials laboratories. The P2 porosity is suited to retaining coarser particles while maintaining acceptable flow rates. Manufactured by Witeg, the funnel belongs to the established range of glass filterware for reliable day-to-day laboratory filtration tasks. Its dimensions allow straightforward connection to common filter flasks and vacuum lines, making it a versatile choice for research, quality-control and teaching environments that require consistent filtration performance without additional accessories.
