Description
Dropping funnel 250 ml NS 19/26 is a cylindrical graduated laboratory dropping funnel intended for controlled reagent addition in synthetic and analytical procedures. It provides a capacity of 250 ml with 5 ml graduations for convenient monitoring of dispensed volumes. The funnel is fitted with an NS-PTFE stopcock plug secured by a threaded stopcock safety lock, cone and socket joints NS 19/26, and a bore of 4 mm. This glassware from manufacturer Witeg comes in packs of 2 pc(s) and is appropriate for organic chemistry, extraction work and general laboratory dosing where reliable dropwise delivery is required. The cylindrical body promotes stable handling and easy reading of the scale, while PTFE stopcock parts contribute chemical resistance toward many common solvents and reagents. Standard NS 19/26 ground joints allow direct connection to matching glassware. It is a practical choice for research, quality-control and teaching laboratories needing graduated dropping funnels with secure stopcock design for accurate liquid transfer.
