Low-temperature fixed bench for biological experiment

The utility model relates to a low-temperature fixed bench for a biological experiment. The fixed bench is provided with fixing clips, a shell body, a water cooling head, a miniaturized water pump, a digital display temperature controller, a magnetic meter seat, a semiconductor chilling sheet, a cold guiding aluminum plate and a power supply. The low-temperature fixed bench is fixed on a steel plate of an electrophysiological air cushion suspension vibration isolation table or experiment table by the magnetic meter seat; the digital display temperature controller is embedded in the shell. The low-temperature fixed bench for the biological experiment has the advantages that the surface temperature of a platform is realized under the ambient temperature condition; the water cooling radiating efficiency is high, the vibration is small, and disturbance to the experiment operation is small; the direct current power supply is adopted for supplying power, and the electromagnetic disturbance to electrophysiological r
