A microplate centrifuge, also known as a microcentrifuge, is a laboratory instrument used to spin small volumes of samples at high speeds in order to separate components based on their density.Microplate centrifuges are commonly used in molecular biology, biochemistry, and clinical laboratories for various applications such as DNA/RNA extraction, protein purification, cell culture, and enzyme assays. They are designed to accommodate multiple samples simultaneously, often in the form of microplates with 96 or 384 wells, allowing for high-throughput processing.
