Description
Liebig condenser in DURAN® glass with NS 14/23 sleeve and core is a straight-tube laboratory condenser designed for vapour cooling in distillation and reflux setups. Its water jacket measures 250 mm in length, offering an extended cooling surface compared with shorter jackets and supporting effective condensation of a wide range of organic solvents and reaction mixtures. Coolant circulates through the outer jacket while vapour passes through the central tube, promoting steady condensate formation for collection or return to the boiling flask. The NS 14/23 ground joints provide a leak-resistant, interchangeable connection to standard small-joint laboratory glassware. Delivered as one piece with a weight of 0,140 kg, the unit mounts readily in common clamp systems and distillation bridges. This Liebig condenser from manufacturer Lenz suits research and teaching laboratories that require durable borosilicate construction and consistent joint geometry. Full transparency of the DURAN® glass allows operators to monitor both coolant flow and condensate behaviour throughout the experiment.

Questions about Liebig condenser, DURAN®, sleeve and core 14/23, jacket L 250 mm, 1 unit(s)
What is this article?
Liebig condenser, DURAN®, sleeve and core 14/23, jacket L 250 mm, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labware.
A reaction vessel is the flask a synthesis actually runs in, sometimes jacketed so a fluid can heat or cool the wall. The joints, the working volume and the jacket connections are the specification. It is not a storage bottle.
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.
