High efficiency air condenser is a waterless glass condenser that requires no cooling water for operation. The glass bellows design provides a high surface area air condenser which is very effective.

  • Performance of the high efficiency air condenser is equivalent to a Liebig type condenser being used with tap water.
  • No risks of water leakage, and potential flooding
  • By not using water the environmental impact is reduced as is the costs of water usage.
  • Clear visibility of the reaction reflux
  • Suitable for use under vacuum
  • High efficiency air condenser is considerably less expensive than other waterless condenser options
  • For solvent volumes from 5ml up to 1 liter
  • Helps meet sustainable water reduction targets

Water-free design: No chiller/circulator needed, Eliminate waste water, No risk of flooding the hood, and No fear of water issues affecting the reflux/reaction due the condenser having reduced water flow or no flow of water.
