Laboratory Centrifuge Equipment; Used to Separate Fluids, Gas, or Liquid, Based On Density

 

Laboratory centrifuge equipment are used to separate materials based on their shape, viscosity, size, and density from the liquid medium in which they dissolve. A centrifuge is a device that uses centrifugal force to separate various components of a fluid. Moreover, it is used to separate cellular element such as red blood cell (RBC) and white blood cell (WBC) from blood sample, separate solid or semisolid precipitant from analytical sample, remove protein precipitate from analytical sample, and to isolate macromolecules such as DNA, RNA, and lipids from cell. There is an increasing demand for durable, reliable, and multifunctional laboratory centrifuge equipment, as they are widely used to conduct a diversity of laboratory work.

It is an important piece of laboratory, operated by a counter-rotating motor that spins rapidly liquid samples at very high speed. In the process of separating different molecules or cells in biological solutions, this equipment also minimizes the amount of time that is wasted during the separation process. Laboratory centrifuge is also commonly used for other purposes, such as medical research and blood banking. Therefore, there is an increasing demand for laboratory centrifuge equipment due to increasing diagnostics and research and development activities.

Laboratory centrifuges are the most indispensable and extensively used centrifugal devices in laboratories all over the world. This particular device has various functions like separating solids from liquid, dextrose from sugar, blood from serum and many more. These instruments come with various names; centrifuges, autosampler, autosidzers, particulate size removers, particulate matter removers, and many more. They are made up of various basic and additional components depending on their use. Some of these elements include motors, turbines, filters, pumps, gearboxes, and many more.

The laboratory centrifuges are usually powered by one or more electric motors. Commonly used options include positive displacement, screw driven, and radial electrics. With regard to the impeller arrangement, they are commonly found in two or three-speed centrifugal force pumps set up wherein the rotors are arranged in the plane of a circle. In the two-speed system, the motor forces the outer and inner rotors at different speeds thus enabling the separation of the various components at high speed. Commonly known as the three-speed system, it is also capable of low and high speed centrifugal force operation.

There are laboratory centrifuges that are used for both experimental and clinical applications. The clinical centrifuges are used in hospitals, clinics, blood banks, and medical research centers for the storage and preparation of blood, tissues, and urine. It is also used for separating cells in bioreactors and in the process of purifying blood and plasma. These clinical centrifuges have separate chambers for each compartment, therefore enabling the separation of different types of cells such as red blood cells, white blood cells, and serum plasma.

Various types of laboratory centrifuge equipment are available in the market, depending on the size and the sample capacity, and are used to separate liquids, gases, or fluids based on density. Moreover, these equipment are extensively used for protein, organelle, virus, cell, and nucleic acid purification, in research and clinical laboratories. Ultracentrifuges, Multipurpose high-speed centrifuges, Clinical centrifuges, and Microcentrifuges are some of the different types of laboratory centrifuges. Laboratory centrifuge equipment are extensively used in the research labs, medical facilities, and many core-industries.
