We all know that sustainability is an essential consideration to how we work in the lab, but you have to feel confident that the solutions you put in place aren’t detrimental to your chemistry. An example of this is waterless condensers, such as CondenSyn® from Asynt.
As one of the most brilliant options available, it now offers you the means to carry out water-free condensing without having to change your processes so not only will you be helping the planet, but you’re saving a fortune in water that’s literally just going down the drain, and making your fume hood a much tidier and safer environment. You can also run overnight reactions without laying awake at night worrying about changes in water pressure causing pipes to pop off and flood your lab, flood your building, and wreck anything electrical in its path.
So what’s stopping you from making this change? Take a look at just some of the incredible feedback we’ve received from scientists who tried our range of CondenSyn® waterless air condensers and bear in mind that payback time is tiny once you get these gems in use!
“We have been trying the CondenSyn® 450 mm air condenser on a THF drying still (b.p. 66 °C), equipped with a 1 L main flask and ~250 mL collection head.
The still runs for approximately 8-9 hours per day. Taking the flow rate of a standard water condenser to be ~0.5 L/min, a rough estimate shows a saving of 240-270 L of water per day.
In all this time, we never observed any appreciable loss of solvent, and while we didn’t measure the temperature at each end of the condenser, the higher temperature at the base caused by the condensing solvent didn’t spread beyond the second ‘rung’.
Aside from the water saving benefits, the main advantages of the CondenSyn are:
• Ease of set-up – can be located anywhere in the fume hood, not restricted to being near a tap/sink.
• No water tubing attachments, so no risk of flooding or water leaks into electrical equipment, as well as reduced fume hood ‘clutter’.
• No need to worry about fluctuating water pressure (or loss of water supply), so refluxing reactions can safely be left overnight.
• Range of sizes for different reaction scales and sizes of flask.”
Dr Graeme McAllister, Experimental Officer, University of York
<The biggest benefits are> No need to worry about the condenser – water tubing connections > eg. reaction setup is so much neater, without a lot of tubing everywhere. no need to disconnect water tubing and having that spill around. overall also less clutter in the fume hood without tubing etc.
Above all, avoids all of the fume hood flood issues we had previously and we can now leave reactions refluxing overnight worry-free.

“We have received a CondenSyn® and have found it to be great, not only in terms of reducing setting up time and clutter but in its performance as well.
We have used it for both refluxing and distillations with a range of solvents and it has stood up to all the challenges.
We found them lightweight and easy to handle. As they don’t require water this benefits the environment as well.
Off the back of this we have ordered some more CondenSyn units.”
Thomas Harman, Development Chemist, Aesica Pharmaceuticals Ltd (UK)
“The use of The CondenSyn® air condensers around the lab have been very helpful! Reducing the need for water condensers for reactions under reflux has improved the efficiency of completing the reactions allowing more to be done at once and allowing experiments to be completed away from a water source. The chances of flooding and water leakage has also been eliminated which is particularly important for overnight reactions etc.”
Oliver Cartright, University of East Anglia, UK
