This appears to be an apparatus for laboratory chemistry. Click on the Netherlands Wikipedia link and see diagrams.

not for reflux
the Liebig condenser is not used for refluxing, the image in the reflux page is wrong. A reflux condenser has a much larger inner surface (not a strait cylinder but a succession of spheres) V8rik 17:02, 2 June 2006 (UTC)


 * V8rik - maybe you're right in that people shouldn't use Liebig condensers when they wish to heat a liquid to reflux, but they are very frequently used for this purpose. -- Quantockgoblin 18:11, 5 February 2007 (UTC)

Which tube is for cooling?
I am not a chemist. When I have seen a Liebig condenser used by a chemist I worked with in a lab many years ago, she ran the cooling water through the inner tube and the gas to be condensed through the outer tube, instead of using the outer tube as a water jacket for the inner tube.

Thinking about this, I can see advantages. The gas to be condensed is exposed to more cooling surface area because the outside surface of the inner tube has a larger area than its inner surface. Furthermore, the gas is exposed to the large-area inside surface of the outer tube, which is at room temperature, for further effectiveness in condensation.

Is that a common practice? If so, perhaps this article should mention it. ~Anachronist (talk) 18:33, 10 October 2023 (UTC)
