Description
Dropping funnel 50 ml with socket NS 29/32 and cone NS 29/32 is a cylindrical borosilicate glass 3.3 laboratory vessel intended for controlled liquid addition in synthesis and analytical work. The graduated body supports accurate volume monitoring, while an integrated pressure equalisation tube maintains balanced internal pressure during use. The outlet tube is fitted with a cone NS 29/32 joint and drip tip, and flow is regulated by a PTFE stopcock NS 12,5 with a 2,5 mm bore that delivers chemical resistance and smooth operation. This dropping funnel from manufacturer Rettberg is supplied as a single piece and connects securely to larger standard ground-joint apparatus. Its 50 ml nominal capacity combined with the larger NS 29/32 joints makes it practical for organic chemistry, pharmaceutical research and dosing applications that require both precision and compatibility with bigger glassware setups. Robust borosilicate glass 3.3 construction withstands typical laboratory conditions, and the drip tip promotes clean, controlled discharge.

Questions about Dropping funnel, 50 ml, graduated, joints size 29/32, stopcock 2,5 mm,
What is this article?
Dropping funnel, 50 ml, graduated, joints size 29/32, stopcock 2,5 mm, is the article on this page. Luminix Health distributes Rettberg 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.
