Description
Dropping funnel 500 ml cylindrical NS 24/29 is an ungraduated laboratory glassware item designed for controlled addition of liquids in synthesis and preparative work. The cylindrical body provides a compact footprint on the bench while the standard ground joints (cone and socket NS 24/29) ensure reliable, leak-resistant connections to common reaction setups. A precision NS stopcock plug with threaded stopcock security allows fine regulation of flow; the bore measures 4 mm for steady droplet or stream delivery. Supplied as a pack of 2 pieces, each funnel has a net weight of 0,512 kg and is intended for routine dosing, extraction support and reagent introduction under atmospheric conditions. Manufactured by Witeg, the funnel suits organic and inorganic laboratories that require durable cylindrical dropping funnels with secure stopcock retention. Ideal for teaching labs, process development and small-scale production where ungraduated cylindrical geometry and NS 24/29 compatibility are preferred. The robust construction supports repeated assembly and cleaning cycles typical of daily laboratory use.

Questions about Dropping funnels, cylindrical, ungraduat
What is this article?
Dropping funnels, cylindrical, ungraduat 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.
