The Bio-Rad PTC-220 DNA Engine® Peltier Thermal Cycler is a reliable, research-grade PCR system widely used in molecular biology laboratories for DNA amplification and thermal cycling applications. Known for its durability and precise temperature control, the PTC-220 remains a trusted platform in academic, clinical, and biotech research environments.

This system utilizes Peltier-based heating and cooling technology to deliver accurate, uniform temperature transitions across the block, supporting reproducible PCR results. The modular design allows compatibility with a variety of interchangeable sample blocks (depending on configuration), making the instrument adaptable to multiple tube and plate formats commonly used in PCR workflows.

The PTC-220 features an intuitive user interface with onboard programming and method storage, enabling users to easily create, save, and recall PCR protocols without external software. Its robust construction and proven performance make it ideal for routine amplification, protocol development, and teaching laboratories.
