Dropping funnels, 100ml, cylindrical,

Dropping funnel 100 ml cylindrical NS 19/26 is a cylindrical, ungraduated laboratory dropping funnel designed for controlled liquid addition and precise dosing in chemical workflows. It features cone and socket joints NS 19/26 together with an NS stopcock plug secured by a threaded stopcock lock, allowing reliable flow regulation through a 2,5 mm bore. The 100 ml capacity suits small-scale synthesis, sample preparation and routine reagent delivery where separate volume measurement is preferred. Supplied in packs of 2 pieces, this model from manufacturer Witeg integrates readily with standard ground-joint glassware assemblies. Its simple cylindrical geometry supports easy cleaning and handling while the threaded stopcock security reduces the risk of unintended opening during operation. Typical applications include dropwise addition in organic reactions, extractions and general wet-chemistry procedures that require steady, adjustable flow. Net weight is 0,126 kg per unit, making the funnel convenient for everyday bench use. The combination of NS 19/26 joints, secure stopcock design and compact volume makes it a practical choice for research, teaching and quality-control laboratories needing dependable dosing funnels.
