<P> The thermal cycler ( also known as a thermocycler , PCR machine or DNA amplifier ) is a laboratory apparatus most commonly used to amplify segments of DNA via the polymerase chain reaction ( PCR ) . Thermal cyclers may also be used in laboratories to facilitate other temperature - sensitive reactions , including restriction enzyme digestion or rapid diagnostics . The device has a thermal block with holes where tubes holding the reaction mixtures can be inserted . The cycler then raises and lowers the temperature of the block in discrete , pre-programmed steps . </P>
