Description
Dropping funnel 250 ml NS 14/23 is a cylindrical, graduated laboratory funnel designed for controlled addition of liquids in synthesis and analytical work. The vessel is graduated at 5 ml intervals for a total capacity of 250 ml and is fitted with a ground joint cone and socket NS 14/23, allowing secure connection to standard glassware assemblies. An NS-PTFE stopcock plug with threaded stopcock lock ensures reliable flow regulation and reduces the risk of accidental opening during operation; the stopcock bore measures 4 mm. Supplied as a pack of 2 pieces from manufacturer Witeg, this dropping funnel is suited to routine dosing, extraction and reaction-feed tasks in organic and inorganic laboratories. The cylindrical body provides a clear view of the liquid level and supports accurate volume control. Net weight is 0,202 kg per unit. Ideal for use wherever precise, dropwise or continuous addition of reagents is required under standard laboratory conditions.
