When you start setting your laboratory, one of the first devices you need to think about is a centrifuge. This is a device that is capable of separate any kind of samples, depending on your needs and tests. High Speed Refrigerated Centrifuge work by a separation method where the components of a sample are separated based on their density according to the centrifugal force they experience. With these devices, samples are spun at > 5000 rpm. This centrifuge type is able to generate a speed of about 60000 g and they are useful to collect microorganisms, cellular debris, larger cellular organelles and proteins precipitated by ammonium sulphate.
