Description
Cylindrical dropping funnel 1000:20 ml K+H NS 24/29 with pressure equalisation, graduated is precision borosilicate laboratory glassware for controlled liquid addition in synthesis and analytical work. The cylindrical body carries clear 1000:20 ml graduation markings for accurate volumetric dosing. Cone and socket joints NS 24/29 enable secure integration into standard ground-joint assemblies. A valve stopcock with PTFE valve spindle and threaded stopcock lock provides reliable, chemically resistant flow control, while the 6,3 mm bore supports efficient transfer of reagents. Integrated pressure equalisation maintains balanced internal pressure during addition, reducing the risk of pressure build-up or interrupted flow. Offered as a pack of 2 pieces with a net weight of 0,527 kg, this dropping funnel from manufacturer Witeg is well suited to preparative organic chemistry, extraction sequences, titration setups and general laboratory dosing where reproducible addition rates and clear volume reading are essential. The combination of graduated scale, PTFE-sealed stopcock and pressure-equalising design supports safe, repeatable handling of solvents and reaction mixtures.

Questions about Dropping funnel cylindrical 1000:20ml C+S ST 24/29
What is this article?
Dropping funnel cylindrical 1000:20ml C+S ST 24/29 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Labware.
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.
