A laboratory microfuge, also known as a microcentrifuge, is a compact, high-speed centrifuge designed for spinning small samples at very high speeds. Typically used in molecular biology and biochemistry labs, it separates substances in a sample based on density, making it essential for tasks such as DNA/RNA extraction, protein purification, and sample concentration. With its small size, it accommodates microcentrifuge tubes or PCR tubes, offering precision and efficiency for high-throughput applications. The microfuge's rapid spinning creates a strong centrifugal force, causing denser components to move to the bottom of the tube, while lighter components remain at the top. This separation process allows researchers to analyse and manipulate microscopic quantities of biological materials effectively.
