Description
Dropping funnel 50 ml cylindrical NS 29/32 is a laboratory glassware component intended for controlled addition of liquids during chemical synthesis, extractions and preparative work. This cylindrical, ungraduated funnel is fitted with an NS stopcock plug and threaded stopcock security that helps maintain reliable flow regulation and reduces the risk of accidental opening. Cone and socket ground joints in NS 29/32 size allow direct connection to standard jointed apparatus, while the 2,5 mm bore supports steady dripping or continuous delivery according to experimental needs. The 50 ml working volume suits small-scale dosing tasks in organic chemistry, analytical procedures and teaching laboratories where separate volume measurement is preferred. Supplied in packs of 2 pieces with a net weight of 0,108 kg, the funnel is manufactured by Witeg and belongs to the categories of dropping funnels with ground joints and dosing funnels. Its cylindrical body facilitates cleaning and visual monitoring of contents, making it a practical choice for routine liquid-transfer operations under typical laboratory conditions.

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.
