CondenSyn® Waterless Air Condenser

The Asynt CondenSyn® Waterless Air Condenser is a unique glass condenser that requires no cooling water for operation.

By using a unique glass forming technique, we have been able to manufacture a high surface area air condenser which is robust and effective.

  • Performance of the CondenSyn® is equivalent to a Liebig type condenser being used with tap water.
  • No issues with water leakage or potential flooding.
  • Being waterless, the environmental impact is reduced as are the costs of water usage.
  • Tidy setup, clear visibility of reflux and easy to clean.
  • Suitable for use under vacuum.
  • Each CondenSyn is individually handmade in the UK.
  • CondenSyn is designed to integrate into multiple systems and applications, with fittings to suit.
  • CondenSyn is considerably less costly than other available systems, but don’t let that put you off!
  • The unique Asynt CondenSyn concept is protected by European Community Registered Designs

The Asynt CondenSyn waterless air condenser shown connects via B24 neck to a round bottom flask. However CondenSyn is available to suit any standard size connection with B19 also very popular.

Independent tests were performed by a leading UK University to evaluate the performance for safe use in their research and teaching laboratories. Evaluations were based upon a basic 350 mm effective length CondenSyn, a 250 mL round bottom flask with 150 mL of solvent.

CondenSyn table of test dataIn these tests the weighed contents were stirred at the given temperature for the stated time to test the loss of solvent, i.e. how much solvent would be lost once the contents have cooled to room temperature.

In a teaching environment the temperature of the heating element is often set higher by students than necessary to ensure a fast heating and vigorous, i.e. clearly visible, boiling of the solvent / reaction mixture. Thus, the temperatures were set to higher values than recommended in research labs for e.g. stills.
*The higher loss of water measured is due to its high surface tension that resulted in droplets of water sticking to the inside of the entire length of the condenser, rather than all running back to the RBF as was observed for all other solvents. **It is recommended that to prevent breakthrough when using solvents below 60 oC boiling point that a temperature differential is kept below 10 oC. With Diethyl Ether then this should be no more than 4 oC.

Saving money and water:

The average rate of water used in a condenser is 2 litres per minute; this rate was confirmed by a major UK research institution as the average measured use per water condenser in their facility. The water costs used below are at £1.50 per cubic metre supply and £1.60 per cubic metre waste which is equivalent to 0.31p per litre. This commercial rate cost is from a water supplier here in the UK, Anglian Water (Wave) in March 2022.
