Description
Separating funnel, pear-shaped, with NS PTFE key, outlet with NS cone and poly stopper is laboratory glassware for larger-scale liquid–liquid extractions and phase separations. Produced from borosilicate glass 3.3 (Boro 3.3) with white inscription and conforming to ISO 4800, it offers a capacity of 500 ml and a sleeve joint of NS 29/32. The PTFE key provides chemically resistant, smooth stopcock control, and the poly stopper secures the top during shaking and settling. The pear-shaped body supports clear phase separation and steady drainage via the NS cone outlet. This model from manufacturer Hecht is intended for chemistry, pharmaceutical and life-science laboratories that require standardized ground-joint connections and robust glassware. White inscription enables quick identification of volume and joint size on the bench. Suitable for solvent extractions, washing steps and preparative sample handling where durable Boro 3.3 construction and reliable PTFE shut-off contribute to consistent, controlled laboratory performance.
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 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.
