Dropping funnel 100 ml K+H NS 29/32 is a cylindrical, graduated laboratory glassware item for controlled addition of liquids in synthesis, titration and general dosing procedures. It features a valve stopcock with PTFE valve spindle and a 2,5 mm bore that enables precise dropwise or continuous delivery. Graduation is marked 100 : 2 ml so that volume can be followed directly on the vessel. Matching cone and socket ground joints NS 29/32 provide secure connection to standard laboratory apparatus. Net weight is 0,137 kg. This funnel from manufacturer Witeg is intended for organic-chemistry and analytical set-ups that require clear scale markings and a PTFE spindle. The cylindrical body offers good visibility of the liquid level throughout addition. Supplied in packs of 2 pieces, it integrates readily into existing ground-joint assemblies used in research and quality-control laboratories for reproducible liquid transfer.
