Findenser™ - saves water and prevents flooding

Findenser is a 'Super air condenser' that replaces water-cooled condensers in over 95 % of common chemistry applications.

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 aircondensers, 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'.

Findenser requires no running water to operate.

Water is a precious resource and 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 the cost of water purchase and disposal
• For solvent volumes from 5 ml up to 1 litre
• Helps meet sustainable water reduction targets

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.

Findenser 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. 

Findenser 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).
