Description
Cylindrical dropping funnel 500:10 ml K+H NS 29/32 with pressure equalisation is a graduated laboratory dosing funnel for larger-volume liquid addition in synthesis and preparative chemistry. The cylindrical body is graduated at 10 ml intervals up to a capacity of 500 ml, giving straightforward visual control of the delivered volume. Cone and socket joints NS 29/32 ensure compatibility with standard ground-joint setups for secure assembly. Flow regulation is handled by an NS PTFE stopcock plug secured with a threaded stopcock lock, offering chemical resistance and reliable shut-off during extended runs. A bore diameter of 4 mm facilitates efficient transfer of aqueous and organic media, while the integrated pressure-equalisation path keeps internal pressure balanced when the funnel is isolated from the atmosphere. Delivered as a pack of 2 pieces with a net weight of 0,372 kg, this dropping funnel from manufacturer Witeg supports reaction feeding, solvent addition and graduated dosing in research, scale-up and quality-control laboratories working with NS 29/32 glassware systems.

Questions about Dropping funnel cylindrical 500:10ml C+S ST 29/32
What is this article?
Dropping funnel cylindrical 500:10ml C+S ST 29/32 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.
