Cryogenic laboratory freezers operating at -150°C to -152°C are advanced cooling systems designed for the preservation of biological materials and sensitive substances that require ultra-low temperatures. These freezers utilise liquid nitrogen or advanced refrigeration technologies to maintain stable conditions, allowing for the long-term storage of samples such as stem cells, genetic materials, and delicate proteins. The extreme cold effectively halts metabolic activity, preventing degradation and ensuring the viability of the samples for future research and experimentation. Equipped with features like safety alarms, monitoring systems, and efficient insulation, these cryogenic freezers provide a secure environment for valuable materials. Their use is critical in biobanks, pharmaceutical research, and advanced scientific studies, where preserving sample integrity is paramount for accurate results and breakthroughs in various fields
