Cylindrical dropping funnel 50:1 ml K+H NS 29/32 with pressure equalisation is a graduated laboratory dosing funnel intended for controlled addition of liquids in larger-scale or wider-neck glassware setups. The cylindrical body is graduated at 1 ml intervals for accurate volume observation during dropwise delivery. A pressure-equalisation arm maintains balanced internal pressure, supporting continuous, uninterrupted flow. Regulation is provided by a valve stopcock with PTFE valve spindle and a 2,5 mm bore. Cone and socket joints NS 29/32 match larger standard ground-glass connections commonly used in preparative chemistry. Supplied in packs of two pieces from manufacturer Witeg, each funnel has a net weight of 0,087 kg. This configuration is well suited to organic synthesis, solvent transfers and reagent dosing where NS 29/32 joints are required, offering reliable metering and chemical resistance for research and production laboratories.

Questions about Dropping funnel cylindrical 50:1ml C+S ST 29/32
What is this article?
Dropping funnel cylindrical 50:1ml 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 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.
