The new high performance CondenSyn MINI is an air condenser optimised for small scale synthetic chemical reactions performed in 5, 10, and 25ml flasks. Individually handmade in the UK, CondenSyn MINI requires no cooling water for operation.
- Performance of the CondenSyn/CondenSyn MINI is equivalent to a Leibig type condenser being used with tap water.
- No issues with water leakage, and potential flooding
- By not using water the environmental impact is reduced as is the costs of water usage.
- A tidy setup, clear visibility of reflux and easy to clean
- Suitable for use under vacuum
- Each CondenSyn/CondenSyn MINI is individually handmade in the UK
- CondenSyn/CondenSyn MINI is designed to integrate into multiple systems and applications, with fittings to suit.
- The CondenSyn system 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 MINI waterless air condenser shown connects via a standard neck to a round bottom flask.
Just 20cm long and fitted with a B14 adapter – the Condensyn MINI provides comparable vapour condensing performance to a Liebig water condenser but advantageously requires no cooling water for operation. While condensers cooled by a circulating water are effective, their constant need for running tap water creates environmental and cost issues.
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 200mm effective length CondenSyn with B19 ground glass joint, a 100ml 2-neck round bottom flask with ~25ml of solvent along with an internal thermometer.
In 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 60C boiling point that a temperature differential is kept below 10oC. With Diethyl Ether then this should be no more than 4oC.

2 This was calculated by mass. The entire apparatus (with solvent) was weighed before and after heating for the stated time, and the loss calculated as a % of the initial weight.
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 £1.22 per cubic metre supply and £1.56 per cubic metre waste which is equivalent to 0.28p per litre. This commercial rate cost is from a water supplier here in the UK, Anglian Water in March 2020.
Every CondenSyn is individually handmade in the UK.
