Outer Sleeve Only, Constant Feed, Condenser, "C" Assembly, Plastic Coated. Outer sleeve for the CG-1333-A-01 condenser. The 19/38 joint is sealed at an angle which allows the condensate to fall into the receiving flask without running down the addition tube into the evaporating flask. This continuous feed feature eliminates the need for a separate filtration step to remove drying agents or other particulate matter from organic solutions prior to rotary evaporation. The ferrule style connection eliminates o-ring connections, which are prone to degradation with long term exposure to organic solvents.
