Description
Separating funnel with glass stopcock is a conical DURAN® laboratory vessel designed for liquid–liquid separations and controlled collection of individual phases. This model combines a glass stopcock with conical form and a capacity of 250 ml, making it suitable for larger routine extraction and partitioning steps. It is supplied as 1 pc and weighs 0,250 kg, remaining manageable for everyday bench and hood work while offering greater working volume. Conical geometry helps the user follow phase boundaries, and the glass stopcock provides direct manual control when draining the lower layer or isolating fractions. DURAN® glass is specified for this separating funnel in the manufacturer data. Available from manufacturer Lenz, the item sits in the separating-funnels segment of laboratory glass, vessels and consumables used throughout chemical and life-science laboratories. The 250 ml capacity supports preparative-scale separations without moving to bulk apparatus. This conical separating funnel is intended for general laboratory use wherever immiscible liquids must be divided cleanly under stopcock control.

Separating funnel, with glass stopcock, DURAN®, conical form, 250 ml, 1 pc is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Separating funnels, inside Funnels, in Labware.
A separating funnel lets two immiscible liquids settle into layers and then runs off the lower one through a stopcock. The shape, Squibb or pear, changes how sharp the interface is as the last millilitres leave. The stopper and the stopcock are both needed.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
