Description
Separating funnel, pear-shaped, with NS PTFE key and poly stopper in Boro 3.3 is laboratory glassware designed for larger-volume liquid–liquid extractions and phase separations. Manufactured to ISO 4800 with clear white inscription, it offers a capacity of 2000 ml and a sleeve joint NS29/32 compatible with common ground-joint setups. The NS PTFE key ensures controlled stopcock operation and good chemical resistance when handling organic solvents and aqueous media, while the polyethylene stopper provides a dependable neck seal. Its pear-shaped profile aids efficient layer settling and precise draining of separated phases during preparative and analytical work. Ideal for chemistry, process development, and life-science laboratories needing robust borosilicate equipment for repeated extraction sequences, this funnel from manufacturer Hecht combines durable Boro 3.3 glass with practical NS joints. It supports reliable separation of immiscible liquids where volume capacity, chemical inertness, and consistent handling performance matter.
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 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.
