AI Technical Summary
The low-temperature storage requirements of paraffin temperature control valves in existing microfluidic chips are difficult to meet. Paraffin valves are prone to deformation or cracking during production. Mechanical valves are complex to design and costly, and there is a risk of reagent contamination due to misoperation.
The microfluidic chip with a phase change valve is used, including a microvalve, an isolator, and a control unit. The control unit controls the microvalve to switch between open and closed positions, the isolator switches between liquid and solid phases to improve sealing, and a positioning pin and a magnetic adsorption structure prevent misoperation.
It achieves good sealing and convenient operation, avoids leakage and reagent contamination, and improves the versatility of the storage environment and production efficiency.
