The difference between medical refrigerators and household refrigerators: The biggest difference between medical refrigerators and household refrigerators lies in the better temperature uniformity control and the wider range of storage temperature options available in medical refrigerators.
So how do we choose a medical refrigerator?
Step 1: We need to clarify what the items to be stored are and what the storage temperature should be.
(1) -86℃ Ultra-low Temperature Refrigerator (Medical Low-Temperature Storage Box): Stores high-value samples such as cells, tissues, test samples, vaccines, bacterial strains, plasmids, viruses, bacteria, red blood cells, white blood cells, and germplasm banks at ultra-low temperatures; also handles material hardening and toughening treatments.
(2) -40℃ Ultra-low Temperature Refrigerator (Medical Low-Temperature Storage Box): Stores seeds, low-temperature materials for experiments, biological products, and frozen plasma.
(3) -25℃ Ultra-low Temperature Refrigerator (Medical Low-Temperature Storage Box): Stores plasma, reagents, and biological materials.
(4) 2~8℃ Medical Refrigerated Storage Box: Refrigerates biological products and reagents.
Step 2: We need to determine the volume of the medical refrigerator based on the size of the space and the quantity to be stored.
Step 3: We need to determine the configuration based on the budget, such as: single-unit self-cascading, dual-unit cascading, and dual independent systems.
(1) Single-unit self-cascading: Single-unit self-cascading effectively saves space, facilitates management and use, and utilizes the cooling effect of the refrigerator itself to improve the cooling efficiency of the entire storage system. For medical institutions requiring large-scale refrigerated storage, single-unit self-cascading is a common storage method.
(2) Dual-unit cascading: Dual-unit cascading saves space and improves cooling efficiency. It is commonly used in hospitals, laboratories, and other places, allowing for the storage of more medicines or reagents and providing a larger cooling space.
(3) Dual independent systems: Dual independent systems can control the temperature and humidity of two storage areas separately, avoiding cross-contamination and infection between different medicines. One system can be used to store medicines, while the other can be used to store other medical supplies, such as vaccines and blood samples. Dual independent systems also have the function of preventing temperature rise during power failure. If one system fails, the other system can still maintain good temperature control to ensure that the stored items are not damaged. By following the three steps above, we can basically determine the model of the medical refrigerator to be selected. Of course, there are many optional items, such as special unlocking methods and remote management software, which can be selected according to actual needs.
