PCR Machines, or thermal cyclers, are essential laboratory instruments used to amplify DNA and RNA sequences through the Polymerase Chain Reaction (PCR) process. These machines precisely control temperature cycles to enable denaturation, annealing, and extension of nucleic acids, making them indispensable in molecular biology, clinical diagnostics, forensic science, and genetic research.

Modern PCR systems offer advanced features such as real-time fluorescence detection, digital quantification, and compatibility with high-throughput workflows. Whether you're conducting basic DNA amplification or complex gene expression studies, there's a PCR machine tailored to your needs.

• Data Connectivity: USB, cloud, or network integration for data management

• Compact & Modular Designs: Space-saving units with scalable capacity

⚙️ Functionality

PCR machines operate through a series of temperature-controlled steps:

1. Denaturation: DNA strands separate at ~94–98°C

2. Annealing: Primers bind to target sequences at ~50–65°C

3. Extension: DNA polymerase synthesizes new strands at ~72°C

These cycles repeat 25–40 times, exponentially amplifying the target DNA. Advanced systems (qPCR and dPCR) monitor amplification in real-time or partition reactions for absolute quantification.
