Description
Dropping funnel 100 ml 2 x NS 19/26 is a cylindrical laboratory dosing funnel with pressure equalisation for controlled reagent addition in closed apparatus. Graduated 100:2 ml and fitted with a drop counter, it enables precise observation and regulation of droplet flow during synthesis, extraction or titration work. An NS-PTFE stopcock plug with threaded stopcock lock secures the valve against accidental opening and provides a chemically resistant sealing interface, while the 2,5 mm bore supports consistent dosing of typical laboratory liquids. Dual standard ground joints NS 19/26 allow direct integration into common glassware trains. Supplied in a pack of 2 pieces with a net weight of 0,118 kg, this dropping funnel from manufacturer Witeg is intended for dosing-funnel and ground-joint applications in research, teaching and quality-control laboratories. The cylindrical body and pressure-equalisation design help maintain steady addition rates without pressure imbalance, making it suitable for routine organic and general laboratory procedures that require reliable, graduated liquid transfer under controlled conditions.

Questions about Dropping funnel 100ml 2 x ST 19/26
What is this article?
Dropping funnel 100ml 2 x ST 19/26 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, 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.
