Quizplus · Accepted Answer

A thermal cycler is specifically designed to automatically change the temperature of the PCR reaction mixture, allowing each step in the cycle to take place with high accuracy and reproducibility. A water bath, ice bucket, thermocoupler, and thermometer are not capable of automatically changing the temperature according to a specific PCR protocol.
