Teperature water baths are essential laboratory devices for maintaining stable temperatures. They operate with heating elements and precise temperature - regulating systems. Water, with its high specific heat capacity, is the heat - transfer medium, enabling gentle and consistent heating. These baths are designed to reach temperatures up to around 100°C. In biological research, they are used for cell culture incubation at 37°C. In chemistry, they control reaction temperatures. Their uniform temperature distribution, achieved through water circulation, is crucial. When using them, safety measures like proper water filling and avoiding overheating are vital. Regular maintenance, including cleaning and thermostat calibration, ensures accurate temperature control and long - term functionality.
