Description
Separating funnel, pear-shaped, with NS PTFE key and poly stopper in Boro 3.3 is laboratory glassware intended for liquid–liquid extractions and clear phase separations. Built to ISO 4800 with durable white inscription, it provides a working capacity of 1000 ml and a sleeve joint NS29/32 for standard ground-joint assemblies. The NS PTFE key delivers smooth stopcock control and broad chemical resistance during solvent work, while the polyethylene stopper seals the neck securely between transfers. The pear-shaped body promotes efficient settling and clean cut-off of organic and aqueous layers in routine analytical and preparative workflows. Suitable for chemistry, pharmaceutical, and life-science laboratories that require robust borosilicate glassware for repeated extraction cycles, this funnel from manufacturer Hecht integrates practical NS joints with reliable Boro 3.3 construction. It supports everyday separation tasks where chemical inertness, mechanical stability, and reproducible handling of immiscible phases are essential.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

What is this article?
Funnel, separating, pear shape with pp stopper, ISO 4800, Boro 3.3, Capacity: is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
