Findenser saves water and prevents laboratory flooding
Replaces water-cooled condensers in over 95% of common chemistry applications
- No risk of water leaks and flooding from running water
- Eliminate the cost of water purchase and disposal
- For solvent volumes from 5ml up to 1 litre
- Helps meet sustainable water reduction targets
How does Findenser work?
- Findenser comprises of an internal glass condenser and an external, finned aluminium jacket, between which a small amount of water is permanently sealed.
- The glass condenser design has a greater internal surface area than traditional air condensers, increasing heat transfer capacity.
- The finned jacket fits around the glass condenser, further increasing the external
- The result is a ‘SUPER air condenser’
How much water are you wasting?
Water is a precious resource. It makes little economic or environmental sense to waste thousands of litres just to cool a single condenser. Whereas Findenser requires no running water to operate.

Findenser return on investment
Compared with a single water condenser, running for just 4 hours a day, Findenser will give you a return on your investment in less than one year.

Findenser performance testing
A range of solvents, in identical flasks and set-ups, were tested with a Findenser, water condenser and air condenser to record solvent loss by weight.
Compared with an air condenser
- For synthesis with ‘low’ boiling point solvents, Findenser showed a significant improvement in solvent retention.
- With acetone or DCM the reaction boiled dry when using an air condenser, yet Findenser retained 95% of the solvent under the same conditions.
- For synthesis with ‘medium’ boiling point solvents, Findenser delivered improved solvent retention particularly with larger volumes and high temperatures.
Compared with a water condenser
Under identical conditions, Findenser retained solvent to the same level as a water condenser (with the exception of diethyl ether).
