Fabric Insulating Top Mantle cover with Power Heating 110V heater attapulgite clay adsorbent it has high heat resistanceInsulating Tops This mantle helps prevent vapor condensation in the upper half of a flask during distillation of high boiling materials. They protect the flask, the solutions, and the laboratory from drafts, which would disturb the reflux ration during fractionation, from flying glass of flask implosions in high vacuum distillations, from falling objects; and, from thermal strain between top and lower half of flask during high temperature operations.
