【Scientific-grade Materials】Featuring a robust PC box body, this freezer box is built to withstand the rigors of cryostorage. The HDPE box cover ensures a tight seal, while the foam liner provides additional protection for your delicate vial and microtube samples
【Optimal Cooling Rate】This cryo box is engineered with a cooling rate close to -1℃/min, significantly raising the survival rate of your cryogenic storage samples
【Gradient Cooling】Utilizing gradient cooling with buffered polycooling, this cryo box maintains a consistent cooling rate without any liquid evaporation, ensuring your samples remain in optimal condition
【Applicability】This cryo box is designed to hold up to 18 tubes, including 1ml, 1.2ml, 1.5ml, and 2ml cryotubes, making it perfect for laboratory use
【Easy to Use】Only 100% isopropanol and mechanical refrigeration equipment are required;Put the unused program cooling box directly in the room, when used directly into the freezing tube and then transferred to -80 °C inside the refrigerator, until the time to use the freezing tube will be removed
