This Glas-Col® mantle helps prevent vapor condensation in the upper half of a flask during distillation of high-boiling materials. 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.
All mantles are 115 Volts.
