Adjustable speed centrifuge is a versatile laboratory instrument designed to separate components of a mixture based on density using centrifugal force. It allows users to precisely control the rotational speed, enabling customization for different applications such as isolating cells, purifying proteins, or separating liquids from solids. The device typically features a rotor that holds sample tubes, which spin at high speeds to generate the necessary force. Adjustable speed centrifuges are essential in fields like biochemistry, molecular biology, and clinical diagnostics, offering flexibility for processing various sample types and volumes. Many models include safety features like lid locks and imbalance detection. Their ability to accommodate different speeds makes them suitable for delicate separations or high-speed pelleting, ensuring efficient and reliable results.
