Description
Dropping funnel 25 ml 2 x NS 14/23 is a cylindrical glass dosing funnel intended for precise addition of liquids in laboratory synthesis and analytical procedures. It combines pressure equalisation with graduation at 25:0,5 ml, a drop counter, an NS stopcock plug and threaded stopcock security. Two NS 14/23 ground joints ensure compatibility with common jointed apparatus, and the 2,5 mm bore promotes controlled droplet flow. Offered by manufacturer Witeg, this 25 ml funnel suits intermediate-scale reagent dosing where both volume readability and joint standardisation are required. The cylindrical form factor remains compact on crowded benches, while the graduated scale and drop counter support visual control during addition. Pressure equalisation assists uninterrupted delivery in closed systems. Applications include organic reaction set-ups, solvent or reagent metering and general preparative work with ground-joint glassware. Supplied as 2 pieces with a net weight of 0,098 kg, the funnel provides a practical mid-range capacity for research, teaching and routine laboratory dosing tasks that rely on NS 14/23 connections.

Questions about Dropping funnel 25ml 2 x ST 14/23
What is this article?
Dropping funnel 25ml 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.
