Description
Funnel with NS stopcock NS 29/32 is a laboratory glass funnel designed for controlled liquid handling, filtration support and transfer operations in analytical and preparative workflows. It incorporates a ground joint together with an NS stopcock, stopcock plug and threaded stopcock security for secure, adjustable flow. Key dimensions include a 60° angle, 90 mm diameter and 6,3 mm bore, allowing efficient drainage while maintaining compatibility with standard NS 29/32 glassware assemblies. Supplied as a single piece, the funnel from manufacturer Witeg integrates readily into existing laboratory setups for chemistry, quality control and research applications. The combination of jointed connection and stopcock enables precise dispensing or interruption of liquid streams during sample preparation, solvent handling or reagent addition. Its geometry supports both rapid pouring and more measured delivery, making it suitable for routine bench work as well as more demanding analytical procedures that require reliable joint sealing and flow regulation.
