Refrigeration bath circulators are ideal for controlling the temperature of connected applications or objects within the thermostat bath. They are commonly used for a variety of applications, such as photometers, refractometers, viscometers, double-jacketed reaction vessels, and autoclaves. These units are versatile and can be used in mini-plants and kilo laboratories, for determining freezing points, for deep temperature calibration, for petroleum tests, for temperature control of measuring devices and experimental setups, as well as for materials testing and quality control. Circulating baths are constant-temperature water baths that provide rapid heating and cooling of samples by constantly circulating water. These baths can efficiently maintain temperatures across a wide range, making them suitable for a variety of applications.
