Stirrer and Hot Plate Selection Guide

Corning combined the unique Pyroceram® glass-ceramic tops with rugged bodies and heating elements in 1964 to come up with the best recognized hot plates and stirrers in the industry. These Pyroceram tops were literally a space age material developed for missile nosecones. (Click here to learn more about this unique material.)
