Similar to CG-1239, but with the condenser being a combination of a cold coil and Liebig. Water flows into hose connection “A” through the coil and exits the outer jacket through hose connection “B”. Head is excellent for use when distilling medium to high boiling point solvents. Top outer joint is a 10/30 for use with a 2” immersion thermometer. Available with or without Vigreux indentations to further improve efficiency.
