Findenser Super Air Condenser

For solvent volumes from 5 ml up to 1 litre

Findenser saves water and prevents laboratory flooding

No risk of water leaks and flooding from running water

Eliminate the cost of water purchase and disposal

Helps meet sustainable water reduction targets

Findenser benefits

Findenser saves water and prevents laboratory flooding, by replacing water-cooled condensers in over 95% of common chemistry applications

No running water required
Findenser comprises of an internal glass condenser and an external, finned aluminium jacket, between which a small amount of water is permanently sealed.
Replace water-cooled condensers
The glass condenser design has a greater internal surface area than traditional air condensers, increasing heat transfer capacity.
Increased heat transfer
The finned jacket fits around the glass condenser, further increasing the external surface area.
Save water, save money
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.

Test conditions: 500 ml solvent in 1000 ml flask for 16 hours, heating 10˚C above boiling point for each solvent.

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 an water condenser

Under identical conditions, Findenser retained solvent to the same level as a water condenser (with the exception of diethyl ether).

Findenser not only removed the worry of possible flooding but as it doesn’t need to be close to a water source it freed up space.James Lynch, Centre for Sustainable Chemical Technologies, University of Bath
