Digital display thermostatic oscillator is a commonly used equipment in biology teaching and laboratory. It combines the functions of constant temperature control and oscillation mixing, and is suitable for biological experiments that require oscillation cultivation at a constant temperature, such as cell culture, microbial fermentation, etc. This device is typically equipped with a digital display screen that can accurately set and display temperature, as well as oscillation speed and time. There are various oscillation modes of constant temperature oscillators, such as reciprocating and rotary, to meet the needs of different experiments. In biology teaching, students can learn the effects of temperature and oscillation on the growth and reaction of biological samples through this device, and master the basic skills of experimental operation.
