Description
Separating funnel, pear-shaped, with NS PTFE key, outlet with NS cone and poly stopper is laboratory glassware intended for liquid–liquid extractions and controlled phase separations. Made from borosilicate glass 3.3 (Boro 3.3) with white inscription and conforming to ISO 4800, it offers a working capacity of 100 ml and a sleeve joint of NS 19/26. The PTFE key delivers smooth, chemically resistant shut-off, while the poly stopper closes the top opening securely during shaking and settling. The pear-shaped body promotes clear phase boundaries and efficient drainage through the NS cone outlet. This model from manufacturer Hecht suits routine analytical and preparative work in chemistry, pharmaceutical and life-science laboratories where standardized ground-joint connections are required. White inscription supports quick visual identification of volume and joint size on the bench. Suitable for solvent extractions, washing steps and sample preparation workflows that demand reliable stopcock performance and durable Boro 3.3 construction under typical laboratory conditions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Funnel, separating, pear shape stem with cone, pp stopper, ISO 4800, Boro 3.3,
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 Round-bottom flasks, inside Beakers & flasks, in Labware.
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.
