This condenser is compact, yet it is as eficient as a standard 400 mm Liebig condenser. It employs a double wall thimble shape bulb sealed into the outer jacket. The detachable hose connections extend through the outer bulb and are made of polypropylene to provide a safe and easy way of connecting and disconnecting flexible tubing to the condenser. It comes supplied complete with two GL-14 open screw caps and two straight polypropylene hose connections. The condensing area is the same as the CG-1217 versions.
