Description
Dropping funnel 500 ml cylindrical NS 29/32 is an ungraduated laboratory glassware component intended for controlled liquid addition in synthetic and analytical workflows. The cylindrical body offers a working capacity of 500 ml and is fitted with an NS stopcock plug that incorporates a threaded stopcock security feature to minimise accidental opening. A 4 mm bore supports adjustable drip rates suitable for many preparative procedures. Both the cone and the socket are finished to NS 29/32, ensuring direct compatibility with standard ground-joint apparatus. This dropping funnel from manufacturer Witeg is well suited to dosing tasks in organic chemistry, extraction sequences and teaching laboratories where an ungraduated cylindrical form is preferred for simplicity and robust handling. Supplied in a pack of 2 pieces, the item provides convenient stock for routine reagent addition, inert-atmosphere work or multi-step reactions that rely on reliable ground-joint connections. The straightforward design facilitates cleaning and repeated use across typical laboratory dosing-funnel applications.

What is this article?
Dropping funnels 500 ml cylindrical ST 29/32 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.
