1, equipment scale and capacity are different: hospitals need large-capacity refrigeration equipment to meet the demand of storing a large number of biological samples or drugs, while individuals buy small-scale liquid nitrogen refrigeration equipment, which is suitable for storing a small number of samples or articles.

2. Temperature control and stability are different: hospital refrigeration equipment has more accurate temperature control system and higher stability to ensure the quality and integrity of stored samples or drugs. In contrast, personal liquid nitrogen refrigeration equipment cannot provide the same degree of precise control and stability.
