Description
Dropping funnel 250 ml 2 x NS 29/32 is a cylindrical laboratory funnel designed for controlled introduction of larger liquid volumes in synthesis and preparative work. Pressure equalisation enables consistent addition under vacuum or inert-gas conditions, complemented by graduation at 250:5 ml and a drop counter for direct observation of droplet rate. An NS stopcock plug with threaded stopcock security delivers dependable sealing and safe handling throughout extended procedures. Both ends carry standard ground joints NS 29/32, allowing ready connection to common reaction assemblies. The stopcock bore is 4 mm to accommodate higher flow when required. Supplied in a pack of 2 pieces at a net weight of 0,245 kg, this model from manufacturer Witeg is appropriate for dosing, scale-up support and general reagent transfer in research and production laboratories. The cylindrical body combines clear level reading with a practical bench footprint for everyday controlled-addition tasks.

A dropping funnel adds a liquid slowly into a closed reaction through a stopcock and usually a ground joint. A pressure-equalising arm keeps the funnel from air-locking. The joint size and the volume are the specification.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
