Molecular analyzers are central to precision medicine and life science research, enabling molecular-level identification by detecting weak fluorescence signals or changes in conductivity. Addressing the transient voltage fluctuations generated by the internal thermoelectric cooler (TEC) during high-frequency thermal cycling, and the stringent electrostatic discharge (ESD) protection requirements of high-sensitivity photomultiplier tubes (PMTs) or CMOS sensors, we offer ultra-low capacitance signal isolation and high-precision power supply voltage regulation solutions. These solutions ensure millisecond-level response of the temperature control system without electromagnetic interference, guarantee the purity of data from complex biochemical reactions, and contribute to achieving extremely low detection limits and excellent repeatability.
