Description
Dropping funnel 50 ml NS 29/32 is a cylindrical, graduated laboratory dosing funnel intended for precise small-volume liquid addition in chemical synthesis and preparative work. With a 50 ml capacity and fine 1 ml graduation intervals, it supports accurate monitoring when only limited reagent volumes are required. Cone and socket joints sized NS 29/32 allow reliable coupling to compatible ground-joint apparatus. An NS stopcock plug with threaded stopcock security provides controlled flow and helps prevent accidental loosening during use. The stopcock bore is 2,5 mm, suited to careful dropwise delivery of reagents. Built according to DIN 12567, the funnel from manufacturer Witeg conforms to established dimensional expectations for dropping funnels with ground joints. Net weight is 0,106 kg, making the unit light and easy to handle on the bench. Typical uses include dropwise addition in organic reactions, small-scale extractions and controlled transfers in analytical or research settings. The cylindrical form promotes stable placement and simple cleaning. Pack size is 2 pieces, ready for integration into standard NS 29/32 glassware trains across laboratory workflows.

Questions about Dropping funnels 50ml ST 29/32
What is this article?
Dropping funnels 50ml 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.
