The invention discloses a DSC electrode system capable of applying an electric field. The DSC electrode system comprises a differential scanning calorimeter, a computer, a signal generator, a self-pressurization liquid nitrogen tank, and a reference crucible; the self-pressurization liquid nitrogen tank is connected with the differential scanning calorimeter, and used for controlling the temperature in real time; the differential scanning calorimeter is connected with the computer and used for transmitting a signal and recording an experiment result; the system further comprises a microelectrode crucible, the microelectrode crucible comprises a ceramic crucible, a ceramic crucible cover, a welding point, 2 electrodes and electrode lead lines which are fixed in the ceramic crucible; the gapis formed between the electrodes to store a tested sample; the welding points are remained on the upper ends of the electrodes, one end of each electrode lead line is connected with the welding point, and the other end is connected with the signal generator and used for applying electric field to the electrode. The invention further provides application of the DSC electrode system capable of applying electric field in the low-temperature storage of the biological and material field. The DSC electrode system can effectively inhibit the low-temperature damage of the biological material, and thelow-temperature storage efficiency of the biological material is improved.
