Beschrijving
Separating funnel, pear-shaped, with NS PTFE key, outlet with NS cone and poly stopper is compact borosilicate glass 3.3 ware for small-volume liquid–liquid extraction and phase separation. Conforming to ISO 4800 with white inscription, it has a 50 ml capacity and a sleeve joint NS19/26. The pear shape concentrates the interface near the stopcock for precise cut-off of the lower layer, while the PTFE key resists many organic solvents and enables fine flow control. An NS cone on the outlet supports grounded connections in the drain path, and the polyethylene stopper closes the neck during shaking. Borosilicate 3.3 glass provides chemical resistance and thermal stability for repeated micro- and semi-micro work. Offered as 1 piece from manufacturer Hecht, this funnel fits analytical sample preparation, method development and teaching labs where a small pear-shaped separator with PTFE key and NS outlet is preferred.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

What is this article?
Funnel, separating, pear shape stem with cone, pp stopper, ISO 4800, Boro 3.3, is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
