Microfield 12 Bucket Centrifuge is a laboratory device used to separate components within a liquid sample based on density, primarily utilized for applications like blood analysis, clinical testing, and biochemistry where multiple samples need to be processed simultaneously, with its 12 individual buckets allowing for the spinning of 12 different samples at once; key features include adjustable speed, automatic balance adjustment, and often, a cooling function to maintain sample temperature during centrifugation.
