Description
Dropping funnel 50 ml K+H NS 14/23 is a cylindrical, graduated laboratory glassware item intended for controlled addition of liquids in synthesis, titration and general dosing work. It carries a valve stopcock with PTFE valve spindle and a 2,5 mm bore that permits precise dropwise or continuous delivery. Graduation is marked 50 : 1 ml so that volume can be monitored directly on the vessel. Matching cone and socket ground joints NS 14/23 allow secure connection to standard laboratory apparatus. With a net weight of 0,081 kg, this compact funnel from manufacturer Witeg fits routine organic-chemistry and analytical set-ups where clear scale markings and a PTFE spindle are required. The cylindrical body gives good visibility of the liquid level throughout the addition. Supplied in packs of 2 pieces, the funnel integrates readily into existing ground-joint assemblies used in research and quality-control laboratories for reproducible liquid transfer.
