Findenser™ - prevents flooding and saves water

Logo_Radleys_Interchim_0416 Findenser FAQs

Findenser requires no running water to operate. Water is a precious resource. It makes little economic or environmental sense to waste thousands of litres just to cool a single condenser.

What are the benefits?

  • No risk of flooding from running water
  • Eliminate water purchase and disposal costs
  • For solvent volumes from 5ml up to 1 litre
  • Helps meet sustainable water reduction targets

Findenser - performs as well as a water condenser
Findenser replaces water-cooled condensers in over 95% of common chemistry applications

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).


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 condensers, increasing heat transfer capacity.
    • The finned jacket fits around the glass condenser, further increasing the external surface area.
    • The result is a "SUPER air condenser".
