Product Overview
A separating funnel has the shape of an inverted pointed flask with a stopcock to drain the contents at its tip. In liquid-liquid extractions, the two immiscible liquids separate into different layers where the liquid with the higher density collects in the lower part of the vessel and can be drained off via the stopcock.

Boro 3.3 Borosilicate glass 3.3 has a very good chemical resistance, virtual inert behavior, a high maximum usage temperature, high light transparency and minimal thermal expansion. Borosilicate glass 3.3 has a linear coefficient of expansion of 3.3 × 10−6 K−1 at 20 °C. It also conforms to the requirements of a USP/EP/JP Type 1 neutral glass suitable for use by the pharmaceutical industry. The properties of DURAN® are specified to ISO 3585 and ASTM-E438 Type 1 Class A.
