Description
Spherical separating funnels with 100 ml capacity and NS 19/26 joint enable reliable liquid-liquid extraction and phase separation in analytical and preparative work. Made from borosilicate glass 3.3, these ungraduated funnels are fitted with an NS-PTFE stopcock featuring a 2,5 mm bore and a PE stopper for secure sealing and broad chemical compatibility. The spherical body promotes clean phase boundaries while the standardised NS 19/26 ground joint ensures interchangeability with common laboratory glassware. Supplied in packs of 2 pieces, each funnel has a net weight of 0,078 kg. These units from manufacturer Witeg support everyday extraction, washing and partitioning steps with aqueous and organic systems. Borosilicate glass 3.3 combined with the PTFE stopcock components provides mechanical strength and low contamination risk under typical laboratory conditions. The funnels are suitable for teaching, quality-control and research settings that require consistent performance in separation workflows.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel globe shaped 100ml ST 19/26
What is this article?
Separatory funnel globe shaped 100ml ST 19/26 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Separating funnels, inside Funnels, in Labware.
A separating funnel lets two immiscible liquids settle into layers and then runs off the lower one through a stopcock. The shape, Squibb or pear, changes how sharp the interface is as the last millilitres leave. The stopper and the stopcock are both needed.
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.
