Description
Dropping funnel 50 ml NS 14/23 is a cylindrical graduated laboratory funnel designed for controlled liquid addition in chemical synthesis and analytical procedures. Equipped with a drop counter and a PTFE stopcock plug featuring threaded securing, it permits accurate drop-wise dosing without pressure equalisation. Dual NS 14/23 ground joints and a 2,5 mm bore provide secure connection to standard glassware while ensuring steady flow characteristics. Clear graduations at 1 ml intervals cover the entire 50 ml working volume, enabling reliable volume tracking during reagent delivery, extractions or multi-step reactions. With a net weight of 0,092 kg the funnel remains easy to handle on the bench. This model from manufacturer Witeg is supplied in packs of 2 pieces and is well suited to organic chemistry, process development and educational laboratories that rely on ground-joint apparatus. The cylindrical body and visible scale support continuous visual monitoring of liquid levels, while the chemically resistant PTFE plug accommodates common laboratory solvents and reagents. The design without pressure equalisation is ideal for applications performed under ambient atmospheric conditions.

Questions about Dropping funnel 50ml ST 14/23
What is this article?
Dropping funnel 50ml 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.
