The sample placing structure of the traditional spin freezing instrument is relatively single, and is usually a sample holder sample groove with fixed specifications. This has poor adaptability to samples with different shapes and sizes. In scientific research experiments, different specifications of centrifuge tubes and culture dish sample containers may be involved. The traditional spin freezing instrument cannot properly fix these samples, and the samples are easy to shake or even fall off during the rotation freezing process, which affects the freezing effect. Moreover, the traditional sample placing structure cannot be flexibly adjusted according to the number of samples. When the amount of samples is small, the space utilization rate is low. When the amount of samples is large, it cannot meet the placing requirements. In small-scale cell experiments, the large size of the sample holder of the traditional spin freezing instrument causes waste of space and makes it difficult to fix a small number of sample tubes, increasing the difficulty of experimental operation. Moreover, the uniformity and stability of the temperature around the samples during the freezing process are crucial to the freezing effect. The refrigeration system of the traditional spin freezing instrument has certain defects in temperature control, and temperature fluctuations are easy to occur. For example, some biological enzymes and proteins may lead to a decrease in activity and changes in structure. Moreover, the temperature response speed of the traditional spin freezing instrument during startup and stop is slow, and it cannot quickly reach and stabilize at the set temperature, further affecting the consistency of the freezing effect.
