Glas-Col 100A MO1143 Heating Top for Fabric Mantles, 5,000ml Flask Capacity, 115V

This mantle helps prevent vapor condensation in the upper half of a flask during distillation of high-boiling materials. The tops are designed for use with Series M, TM, or STM mantles. They protect the flask, the solutions, and the laboratory in these ways: 1) from drafts, which would dis-turb 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, the elliptical hole accommodates 1-, 2-, and 3-neck flasks.

• For use with flask of 5,000ml capacity and 220mm diameter
