We sell high quality used Liebig condensers from European top brands, such as Schott Duran, at 40 % of the new price. Every piece of glassware is “as new” and has been controlled and cleaned before offering them for sale. If a piece of glassware is very slightly damaged, than we sell this piece as B quality glassware. B quality glassware functions properly and is a lot cheaper. For the used laboratory glassware we limit ourselves to the Dutch market as the transportation costs to other countries probably exceed the savings in buying used glassware.
Liebig Condensers are the most common condensers and the cheapest. They consist of an inner tube surrounded by an outer tube. The coolant flows through the outer tube and the substance gets condensed in the inner tube. It is only effective with substances that have boiling points of around 100ºC or higher. It can be used in distillations as well as refluxes.
