Findenser Super Air Condenser

For solvent volumes from 5 ml up to 1 litre

Findenser saves water and prevents laboratory flooding

No risk of flooding from running water, unlike a water cooled condenser

Water free condenser eliminates water purchase and disposal costs

Helps meet sustainability and water reduction targets

Findenser benefits

Findenser air condenser – the sustainable condenser alternative to water condensers. Replaces the need for water-cooled reflux condensers in over 95% of all 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
Findenser super air condenser is a waterless air condenser: 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’! Findenser condenser removes the need for water cooling, giving labs a green option as a glass condenser replacement.

Findenser saves water and prevents laboratory flooding

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 a water condenser

Under identical conditions, Findenser retained solvent to the same level (within the limits of experimental error) as a water condenser with a range of solvents. Diethyl ether is not recommended for use with Findenser.

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
