Description
Cylindrical dropping funnel 250:5 ml K+H NS 14/23 with pressure equalisation, graduated is a precision glassware item for controlled addition of liquids in synthetic and analytical laboratory work. The cylindrical body is graduated and offers a 250:5 ml capacity scale, while the NS 14/23 cone and socket joints ensure compatibility with standard ground-joint apparatus. A pressure-equalisation design maintains balanced internal pressure during addition, and the stopcock features an NS plug with threaded stopcock retainer for secure operation. The bore measures 4 mm and the funnel conforms to DIN 12567. Net weight is 0,28 kg. Supplied in packs of 2 pieces from manufacturer Witeg, this dropping funnel supports accurate dosing, extraction and reaction set-ups where graduated cylindrical geometry and pressure equalisation improve handling safety and reproducibility. It is well suited for organic synthesis, preparative chemistry and general laboratory dosing tasks requiring reliable ground-joint connections and controlled liquid transfer.

Questions about Dropping funnels cylindrical 250: 5ml C+S ST 14/23
What is this article?
Dropping funnels cylindrical 250: 5ml C+S ST 14/23 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.
