Description
Liebig condenser, DURAN®, is a straight-tube laboratory condenser intended for vapour cooling in distillation and reflux work. It combines a standard ground joint NS 29/32 with a 250 mm jacket length and integral glass hose connectors, allowing secure attachment of cooling-water lines in common glassware trains. Manufactured from chemically resistant DURAN® borosilicate glass, the condenser withstands typical thermal cycling and solvent exposure encountered in organic synthesis, teaching laboratories and quality-control distillations. The classic Liebig geometry provides a continuous cooling jacket around the vapour path, supporting efficient condensation when paired with an appropriate coolant flow. Supplied as one piece with a net weight of 0,186 kg, the unit fits standard NS 29/32 assemblies without additional adapters. This model from manufacturer Lenz is suited to preparative and analytical setups that require reliable, reusable glass condensers. Its standardised joints and robust construction make it a practical component for everyday distillation, extraction and solvent-recovery applications across research and industrial laboratories.

Questions about Liebig condenser, DURAN®, w. glass hose conn. NS 29/32, L 250 mm, 1 unit(s)
What is this article?
Liebig condenser, DURAN®, w. glass hose conn. NS 29/32, L 250 mm, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
