The thermal cycler heats and cools the reaction tubes to achieve the temperatures required at each step of the reaction see below. Many modern thermal cyclers make use of the Peltier effect , which permits both heating and cooling of the block holding the PCR tubes simply by reversing the electric current. Thin-walled reaction tubes permit favorable thermal conductivity to allow for rapid thermal equilibration.
