Description
Separating funnel Walter 100 ml NS 19/26 is a compact, ungraduated Walter-type funnel made from borosilicate glass 3.3 for small-scale liquid–liquid extractions and phase separations. The 100 ml body features ground joint NS 19/26, an NS-PTFE stopcock plug with 2,5 mm bore and a PE stopper, enabling precise control of phase release and a tight seal during mixing. Its ungraduated form is well suited to micro- and semi-micro work where solvent economy and rapid handling matter, while borosilicate glass 3.3 delivers the chemical durability needed for common organic and aqueous systems. The NS 19/26 joint matches standard small-scale glassware. Available as a pack of 2 pieces from manufacturer Witeg, the funnel supports teaching, method development and analytical sample work-up. Net weight is 0,25 kg. The Walter profile together with the PTFE plug favours clean drainage and easy cleaning between successive separations in busy laboratory environments.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel Walter 100ml NS 19/26
What is this article?
Separatory funnel Walter 100ml NS 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.
