Centrifuge is a device that is used to separate particles from a solution that vary according to their sizes, shape and density. A centrifuge is considered as an indispensable instrument for laboratory procedures. And the process that is carried out by these devices is centrifugation. Centrifugation has been widely adopted and is considered as the most effective way of separating samples from components. These samples are of various densities, some are highly dense while some are low in density.

Centrifugation uses centrifuge for sedimentation of mixtures that are frequently used in industry and laboratory. A centrifuge generally has an electric motor that places an object in rotation which is done in fixed axis applying perpendicular force to the axis. This device works on the sedimentation principle, where lighter objects move on the top and heavier particles settle down at the bottom.

These devices are available in several models and designs. There are different prime factors that people usually consider while purchasing a centrifuge. These factors in some way or the other ensure the durability of a product such as the device should be easy to use, reliable and the most important that it should be safe. Safety features such as zero RPM lid lock and auto unbalance detection, rotor recognition and shut down are integrated in these models. Compared to the General Purpose Centrifuge the small laboratory centrifuge is smaller in size and it ensures much more convenience for many of its users. This centrifuge is easily movable i.e. from one place to another and is incorporated with advanced technologies.

There are centrifuges used for biological research and are known as micro centrifuges. These are used to process extremely small volumes of biological molecules and they generally hold 0.5 – 2ml of liquid and work at the maximum speed of 12000-13000 rpm. These centrifuges are small enough to fit the table top and they possess rotors that can quickly change the speed. High speed centrifuge are the ones who are capable of handling larger samples volume from a few tens of milliliters to several liters. They can also reach higher angular velocity and its rotors come with different adapters that can hold equipments of various sizes like test tubes, bottles or micro titer plates. Compared to the above stated centrifuges, ultra-centrifuge can isolate smaller particles such as ribosomes, proteins and viruses and can also be used in the study of membrane fractionation. Moreover, ultra-centrifuge can be also used to separate molecules in a batch or constant flow systems.
