Thermal cycler

（重定向自Thermocycler）

'Baby Blue', a prototype automated thermocycler built around 1986.

A very early PCR machine. Rather than cycling through different temperatures, it uses three different water baths at constant temperature between which samples are moved with a robotic arm.

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.
