Protecting valuable biological materials requires reliable, ultra-low temperatures. While –80 °C freezers remain widely used for general biobanking and molecular biology samples, certain applications, including regenerative medicine, reproductive cells and advanced therapies, demand colder, more stable storage. Traditionally, cryogenic storage has meant liquid nitrogen (LN₂) tanks. Today, cryogenic freezers achieve –150°C using advanced mechanical refrigeration
