As a core module of the gene sequencer, the reagent storage system provides a stable low-temperature refrigeration environment for sequencing reagents. The system mainly consists of three parts: sampling mechanism, reagent storage chamber, and temperature control system. The temperature control system adopts a design combining a thermoelectric cooler(TEC) and air cooling, balancing cooling efficiency, operational stability, and structural miniaturization, enabling the reagent storage chamber to meet the refrigeration temperature requirements of sequencing reagents at(6±2) ℃. Test results demonstrate that the temperature control system reliably achieves a temperature control accuracy of(4±0.5) ℃, and the reagent storage chamber meets the requirement of refrigeration temperature at(6±2) ℃ for sequencing reagents. In summary, the proposed design of the reagent storage system complies with relevant industry specifications, provides a valuable reference for subsequent optimization and development of reagent storage systems for gene sequencers. It is of significant importance in promoting the localization process of the sequencing instruments and enhancing the independent controllability of its core technologies.
