Description
Dropping funnel 250 ml NS 29/32 is a cylindrical, graduated laboratory funnel for controlled liquid addition in synthesis, extraction and analytical workflows. It combines a ground joint core and socket NS 29/32 with an NS stopcock plug protected by a threaded stopcock retainer, ensuring a secure seal and reliable flow through the 4 mm bore. Clear 5 ml graduations across the 250 ml working volume support accurate dosing and volume monitoring. Built to DIN 12567, the funnel from manufacturer Witeg integrates readily with standard ground-joint glassware trains. The cylindrical body provides good visibility of the liquid column while the stopcock design allows both dropwise and continuous delivery. Supplied as a pack of 2 pieces with a net weight of 0,24 kg, it is suited to preparative chemistry, reagent addition, titrations and general dosing tasks in research, teaching and quality-control laboratories that rely on interchangeable NS joints.
This article is part of Dropping funnels, in Funnels.
