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 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
