Patent ID: 8367422

Claim:
A method of controlling an internal temperature of a biochemical analyzer comprising: a microfluidic device loading space which receives a microfluidic device, the microfluidic device loading space comprising a microfluidic device supporting unit detachably supporting the microfluidic device; an energy source loading space which receives an energy source, the energy source applying the energy to the microfluidic device; an isolation wall isolating the microfluidic device loading space from the energy source loading space to prevent heat transfer between the microfluidic device loading space and the energy source loading space, the isolation wall comprising a window through which the energy can be transmitted; a heater which heats the microfluidic device; and a first temperature sensor which measures a temperature of the microfluidic device loading space, the method comprising: measuring the temperature of the microfluidic device loading space using the first temperature sensor; and operating the heater if the measured temperature is lower than a first reference temperature.
