The Greener Alternative to Water Condensers

Conventional reflux condensers are used for syntheses under reflux and the tubing they require takes up a lot of space. It is not uncommon for the tubing to snap off due to the water pressure or for leaks to occur, causing major damage in the laboratory.

From now on refluxing can happen without water!
The Findenser™ is a high performance condenser and replaces the need for water-cooled condensers in over 95 % of all reflux reactions.


Patented design:

The Findenser™ consists of a glass column and a finned aluminum housing jacket. A small amount of encapsulated thermal fluid that is located between the glass column and the aluminum jacket transfers the heat from the glass to the finned aluminum jacket.
The heat generated in the process is then dissipated to the outside via the innovative structure of the aluminum fins. The large surface of the aluminum fins thus guarantees an excellent heat transfer.
When used in the laboratory fume hood, the Findenser™ offers a cooling capacity that is in no way inferior to water-cooled systems.


Your advantages in the laboratory:

Leading Safety Standards
No danger of leaks or flooding – the Findenser™ is also suitable for continuous operation, for instance overnight

Superior Ease of Use
Easy handling, no tubing – the Findenser™ is easy to assemble, offers more space in the laboratory fume hood and a highly flexible use

Reduced Cost of Ownership
No water connection required, no water consumption – the Findenser™ is resource-friendly and inexpensive


There are two Findenser™ models available:

Findenser™ Standard (400 mm) and Findenser™ Mini (275 mm). The different lengths are suited for the following solvent volumes:
Findenser™ for solvent volumes of up to 1 liter
Findenser™ Mini for solvent volumes of up to 125 ml

Each Findenser™ model is available with different ground glass cones / sockets, suitable for the glass flasks commonly used in the laboratory.
Findenser™: B19, B24, B29
Findenser™ Mini: B14, B19, B24



Understanding the air cooled reflux system

Increased requirements on safety and sustainability in the chemical laboratory have been the trigger for the development of new reflux condensers without water cooling.
