Ultra-low temperature freezer cryopreservation box, also known as ultra-low temperature freezer. Is mainly used in biological samples, or the preservation of the drug. Cryogenic refrigerator temperature ranges from - roughly 60 ℃ to - 150 ℃ degree. The correct use of cryogenic refrigerator operation is helpful to prolong the life and its proper use.
1, ultra-low temperature freezer no-load ( Do not put items) , boot, phased make cryogenic refrigerator cooled to 40 degrees - first, normal stop and then fall to - 60 degrees, the normal open stop eight hours and then transferred to - 80 degrees, freezers for normal open 24 hours.
