Glas-Col Heating Mantle Top, 5000mL Capacity, 300 Watts. This Glas-Col mantle helps prevent vapor condensation in the upper half of a flask during distillation of high-boiling materials. The top is designed for use with CG-11000, CG-12000 or CG-125000 mantles. It protects the flask, the solutions, and the laboratory in these ways: 1) from stray drafts, which would disturb the reflux ratio during fractionation; 2) from flying glass of flask implosions in high-vacuum distillations; 3) from falling objects; and, 4) from thermal strain between top and lower half of flask during high-temperature operations. With a glass-fabric construction and laced-side opening, its elliptical hole accommodates a 1, 2, and 3-neck flask. All mantles are 115 Volts with the exception of the 72 Liter which is 230 Volt, and have a 4 foot, 2 wire cord with locking connector.
