Corning® 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.) Today there are many more products with the white Pyroceram tops with more robust electronic controls and even digital LED displays.
