Description

A compact fractionation unit for distilling small quantities in a vacuum, and for ordinary separation. Column is vacuum jacketed. The indents are positioned to cause the vapor to follow a spiral path. Approximately three theoretical plates at 60mL/hr. Hold up to 1.2mL operating, 0.5mL static. Receiver capacity is 15mL. By use of the three-way stopcocks, a manifold arrangement is achieved, making it possible to remove receivers without disturbing the equilibrium of the system. 10/30 thermometer joints are for 25 mm immersion thermometers.
