MICROFLUIDIC DEVICE FOR THE TEMPERATURE-CONTROLLED PROCESSING OF A SAMPLE SOLUTION

摘要

The present invention relates to the temperature control of a kind of microfluidic device (400) processing sample solution (410) to have reaction chamber (450), and wherein the sample solution (410) can be heated to target temperature close to the sample solution of normal boiling point. According to the present invention, the reaction chamber (450) is in the pressure chamber (460) being in fluid communication and passes through compensation channel (422), these pressure chamber's aneroids are in normal operation, the normal boiling point sample solution (410) that temperature is higher than can be heated to, be designed to the amount of evaporation liquid by (464) (454) pressing bubble in sample solution feed pressure room (460) by compensation channel (422), so that pulse back-pressure to sample solution is present in reaction chamber (410) (450) 0 in reducing.
