Corning plate can't be heated in a steamer, and it is easy to crack or deform, thus affecting the experimental results. To heat Corning plate, it is necessary to use special heating appliances, such as constant temperature incubator and constant temperature water bath, to ensure the accuracy and safety of the experiment. Corning plate is a commonly used experimental vessel in life science laboratory, which is usually used to cultivate and observe cells. Corning plates are usually made of heat-resistant glass or plastic and can withstand certain temperature changes. Corning plates are not suitable for heating in a steamer.
