Description
Dropping funnel 2000 ml cylindrical NS 29/32 is a large-capacity ungraduated cylindrical laboratory funnel intended for controlled addition of liquids in preparative and process-scale work. The two-litre cylindrical body accommodates substantial reagent volumes while cone and socket joints NS 29/32 ensure standardised, tight connections to reaction apparatus. An NS stopcock plug with threaded stopcock security provides secure, adjustable flow regulation; the 6,3 mm bore permits steady droplet or stream delivery according to experimental needs. Supplied as 1 piece, the funnel has a net weight of 0,824 kg and is suitable for bulk dosing, solvent introduction and larger-scale work-up under ordinary laboratory conditions. Produced by Witeg, this cylindrical dropping funnel serves organic synthesis, pilot laboratories and teaching facilities that require ungraduated 2000 ml geometry with NS 29/32 compatibility. Robust glass construction supports repeated assembly, cleaning and long-term use where reliable stopcock retention and standard joint interfaces are mandatory for safe, reproducible liquid handling.

Questions about DROPPING FUNNELS, CYLINDRICAL, UNGRAD.,
What is this article?
DROPPING FUNNELS, CYLINDRICAL, UNGRAD., is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Entonnoirs à addition, inside Entonnoirs, in Matériel de laboratoire.
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.
