Temperature control is a core component of PCR equipment, utilizing the Xilinx STM32F103ZET6 as the main chip, which is responsible for accurately controlling the reaction temperature to ensure the smooth progress of the PCR reaction. Precise control of the heater and cooling system is achieved through the microprocessor and temperature sensors, meeting the temperature requirements for different steps such as DNA denaturation, annealing, and extension. The product's channel management strictly follows the original manufacturer or first-tier agency model, ensuring the reliability of the supply chain and the high quality of the product.
