Thermocycler

A thermocycler is a laboratory device used in DNA research. It performs a process called polymerase chain reaction (PCR), which helps amplify small samples of DNA to generate enough material for analysis. The thermocycler carefully controls the temperature, cycling through different heat levels to separate the DNA strands, attach primers (short DNA pieces), and replicate the strands. This technique is essential for various applications, including genetic testing, cloning, and disease diagnosis, making it a cornerstone tool in molecular biology and genetics.
