Laboratory centrifuge is a vital instrument used to separate components of a mixture based on density through centrifugal force. It works by spinning samples at high speeds, causing denser particles to move outward and settle at the bottom, while lighter components remain closer to the top. This process is essential for applications such as isolating DNA, purifying cells, separating blood components, and analyzing proteins. Centrifuges come in various types, including benchtop, microcentrifuges, and ultracentrifuges, each designed for specific sample volumes and speeds. They are widely used in medical, biological, and chemical laboratories for research, diagnostics, and quality control. Modern centrifuges often feature programmable settings, temperature control, and safety mechanisms to ensure precise and reliable results. Their versatility makes them indispensable in scientific and clinical workflows.
