Water Jacketed incubators are used in the lab setting to maintain temperatures for controlling biological samples or organisms. It works by using water regulate the temperature inside of the incubator. These incubators are comprised of two chambers: The inner chamber where the samples are placed and the outer chamber which contains the heated water. The water temperature is controllable and heats the inner chamber through the walls of the incubator. Water jacketed incubators are commonly used in research laboratories, especially in fields like microbiology, cell biology, chemistry, and genetics.
