Description
Dropping funnel 500 ml cylindrical NS 19/26 is a cylindrical, ungraduated laboratory dropping funnel built for controlled liquid addition and larger-volume dosing applications. It incorporates cone and socket joints NS 19/26 plus an NS stopcock plug with threaded stopcock security, enabling reliable flow regulation through a 4 mm bore. The 500 ml capacity accommodates medium- to larger-scale synthesis, extractions and reagent delivery where separate volume measurement is preferred. Supplied in packs of 2 pieces, this model from manufacturer Witeg mates readily with standard ground-joint glassware. The straightforward cylindrical geometry aids cleaning and content visibility, while the threaded stopcock lock contributes to operational safety. Net weight is 0,508 kg per unit. Typical uses include dropwise addition in organic reactions, preparative work and general wet-chemistry procedures requiring steady, adjustable flow. With its NS 19/26 joints, secure stopcock design and generous volume, the funnel serves as a practical dosing tool for research, teaching and quality-control laboratories that need dependable performance in everyday liquid-handling tasks.
