Selecting a Suitable Chiller for Your Rotary Evaporator

Selecting a Suitable Chiller for Your Rotary Evaporator

Apr 04, 2019 A chiller is an important part of many rotovap setups as it’s responsible for cooling the coolant that flows through the condenser. It’s possible to avoid purchasing a chiller, for example by using a dry ice condenser or juryrigging your own chiller, but in most cases, a suitable chiller will be needed.. When shopping for an appropriate chiller for your setup, the most …

Apr 11, 2016 If your vapor temperature is high enough, you can simply use water. You can use a recirculating chiller to cool the water or you can simply connect the condenser to a tap. Don't forget the Rule of 20 - you want the coolant to be at least 20C cooler than your vapor temperature. If you need your coolant to be near or below 0C you cannot use ...

What Are Rotovaps and How Can They be Used?

What Are Rotovaps and How Can They be Used?

The benefit to using a rotovap over a simple distillation system is that the rotation of the evaporating flask, combined with a heated water bath, increases the surface area of the product. This makes the distillation go faster and keeps the mixture evenly mixed and heated, to promote a stable and even evaporation.
