Description
Büchner funnel 50 ml P4 is a compact glass filter funnel for vacuum filtration in chemical and analytical laboratories. It provides a working capacity of 50 ml together with a filter plate diameter of 35 mm and an outer stem diameter of 10 mm, enabling reliable solid-liquid separation on a small scale. The P4 porosity grade is suited to medium filtration tasks such as collecting precipitates, clarifying solutions or preparing samples for further analysis. With a net weight of 0,043 kg the funnel is lightweight yet stable when mounted on a vacuum flask or filtration assembly. Offered as a single piece, it integrates readily into standard laboratory glassware setups used for organic work-ups, qualitative tests and routine purification steps. Produced by manufacturer Witeg, the funnel belongs to the established family of glass nutsche filters and fritted ware employed across research, quality-control and teaching environments. Its defined plate and stem dimensions ensure consistent seating of filter media and secure connection to receiving vessels, supporting efficient solvent removal and residue recovery without the need for additional adapters in most configurations.
