AI Technical Summary
Traditional stem cell pre-freezing storage devices suffer from problems such as insufficient temperature regulation flexibility, uneven temperature distribution, cold air leakage, and cumbersome operation, which affect the activity and safety of stem cells.
The system employs a threaded column-driven tray lifting structure and a ring-shaped pipe uniform nozzle design, combined with a sealing plate and a pressure relief valve, to achieve tray position adjustment and uniform distribution of cold air, precisely control the cooling rate and temperature, reduce cold air leakage, and ensure the uniformity and safety of stem cell pre-freezing.
This technology enables differentiated temperature control during stem cell pre-freezing, improving the stability and safety of the pre-freezing effect, ensuring the activity and functional integrity of stem cells, and simplifying the operation process.
