Description
Dropping funnel 50 ml 2 x NS 14/23 is a cylindrical laboratory funnel for controlled liquid dosing in preparative chemistry and related analytical work. It features pressure equalisation, graduation at 50:1 ml, a drop counter, an NS stopcock plug and threaded stopcock security for secure operation. Dual NS 14/23 ground joints fit standard jointed assemblies, and the 2,5 mm bore enables steady droplet delivery. This 50 ml model from manufacturer Witeg addresses larger yet still bench-friendly addition volumes where graduation clarity and joint compatibility are essential. The cylindrical body keeps handling straightforward, while the scale and drop counter help operators monitor addition rate and total volume. Pressure equalisation supports smooth flow when the apparatus is closed. Typical uses cover organic synthesis, reagent or solvent metering and general dosing through ground-joint glassware in research or teaching environments. The funnel is supplied in packs of 2 pieces and has a net weight of 0,116 kg, making it a practical choice for laboratories that standardise on NS 14/23 connections and need reliable intermediate-capacity dropping funnels.
This article belongs on Dropping funnels, in Funnels.

What is this article?
Dropping funnel 50ml 2 x 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.
