PCR (Polymerase Chain Reaction) machines—also known as thermal cyclers—are essential instruments used to amplify specific DNA sequences through controlled cycles of heating and cooling. These machines are a cornerstone of molecular biology, genetic research, diagnostics, and biotechnology, enabling precise and reproducible DNA amplification for a wide range of applications. PCR machines work by replicating DNA across numerous cycles, exponentially increasing the amount of genetic material in a sample. This process is vital in workflows such as gene cloning, genotyping, mutational analysis, gene expression studies, and pathogen detection. PCR machines are used in both research laboratories and clinical settings, supporting applications from routine screening to advanced diagnostic testing. There are three main categories of PCR systems: standard thermocyclers, real-time PCR systems (qPCR), and droplet digital PCR systems (ddPCR). Standard PCR thermocyclers are widely used for traditional PCR workflows such as cloning, genotyping, sequencing library preparation, and molecular marker analysis. These machines offer basic temperature cycling programs with precise control and high throughput options. Real-time PCR systems enable quantitative analysis (qPCR) by measuring fluorescence signals during each cycle of DNA amplification. They are essential for gene expression profiling, mutation screening, viral detection, and copy number variation analysis. Advanced models feature multiplexing, high-throughput formats, and fast cycling capabilities. Droplet digital PCR (ddPCR) systems provide ultra-sensitive nucleic acid quantification by partitioning reactions into thousands of droplets. ddPCR is ideal for low-abundance target detection, cancer diagnostics, liquid biopsies, and viral load monitoring.
