The cylindrical dropping funnel 500 : 10 ml K+H NS 19/26 with pressure equalisation is a graduated laboratory funnel for larger-volume controlled addition of liquids. Its cylindrical body is graduated in 10 ml increments across a 500 ml capacity, giving clear volumetric guidance during dosing. Cone and socket ground joints NS 19/26 ensure reliable connection to standard jointed apparatus. Flow control is provided by an NS PTFE stopcock plug with threaded stopcock security, combining chemical resistance with secure operation. A 4 mm bore accommodates higher flow rates suited to the larger working volume. Integrated pressure equalisation keeps internal pressure balanced while liquid is added, supporting safer handling in closed reaction setups. Delivered as a pack of 2 pieces with a net weight of 0,328 kg, this dropping funnel from manufacturer Witeg is well suited to preparative organic chemistry, process development and general laboratory dosing applications that call for a graduated cylindrical funnel with pressure equalisation.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel cylindrical 500: 10ml C+S ST 19/26
What is this article?
Dropping funnel cylindrical 500: 10ml C+S ST 19/26 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Labmateriaal.
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.
