A refrigerated centrifuge is a laboratory device used to separate components of a mixture based on their density. It spins samples at high speeds, creating a centrifugal force that causes denser materials to move to the bottom of the container, while lighter materials remain on top. This process is essential in various fields, including biology and chemistry, for tasks like isolating cells or purifying proteins. The refrigeration feature allows the centrifuge to maintain low temperatures during operation, which is crucial for sensitive samples that may degrade or change at higher temperatures. This capability is particularly important in applications involving biological samples, blood samples, and enzymes, ensuring sample integrity and accuracy in results.
