Beschreibung
Cylindrical dropping funnel 1000:20 ml K+H NS 29/32 with pressure equalisation, graduated is laboratory glassware intended for precise, controlled addition of liquids in chemical and analytical procedures. The cylindrical vessel is graduated 1000:20 ml, allowing clear volume monitoring throughout dosing. Cone and socket joints NS 29/32 ensure compatibility with common ground-joint apparatus. Flow is regulated by a valve stopcock fitted with a PTFE valve spindle, offering chemical resistance and smooth operation; the bore range of 0–6 mm accommodates different transfer rates. An integrated pressure-equalisation path keeps internal pressure balanced during addition, supporting steady delivery without interruption. Supplied in a pack of 2 pieces with a net weight of 0,594 kg, this dropping funnel from manufacturer Witeg is appropriate for preparative synthesis, solvent addition, extraction work and routine laboratory dosing tasks that demand reliable volumetric control. The graduated cylindrical form, PTFE-sealed stopcock and pressure-equalising design together facilitate safe, reproducible handling of reagents in standard laboratory setups.
This article belongs on Dropping funnels, in Funnels.

Questions about Dropping funnel cylindrical 1000:20ml C+S ST 29/32
What is this article?
Dropping funnel cylindrical 1000:20ml 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 Laborbedarf.
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.
