Centrifuges are one of the most important chemistry lab equipment's, centrifuge tube are simple devices usually driven by a motor that woks on the principle of sedimentation. Objects in a centrifuge is rotated around a fixed axis, thus applying a force perpendicular to the axis. The sedimentation principle uses the centripetal acceleration to evenly separate substances of varying density.
A large range of centrifuges are available in market today. Some of them are very generic while some are highly specific. Centrifuges can be divided or categorized on several basis.
Types Of Centrifuge Tube
Usually the centrifuges can be divided in two main categories. They are stationary centrifuges and rotating centrifuges. However both types work on the same principle. Particles of varying masses are set into motion around a common center. The faster the particles rotate, the greater will be the difference with which they separate from their common center, the easier they will be separated.
In the stationary types of Centrifuge Tube , fluids(either gas or liquid) consisting of more than two components are injected at a high speed into a conical or cylindrical chamber. When the fluid moves around the sides of chamber, the components are separated. The heavier substances travel to the outer side while the lighter substances move closer to the center of the cylinder.
For the centrifuges used in laboratories, there are mainly two sizes. The bigger sized ones are simply known as centrifuges in which samples are contained in centrifuge tubes. Smaller laboratory centrifuges are known as micro-centrifuges or microfuges and microfuge tubes are used foe containing sample.
Special purpose centrifuges can be design as per your unique industrial applications. Industrial centrifuges are widely used in all type of industries to separate solid from liquid. In industries, the mixture of liquid and solid needs to be separated. The centrifuge makes it possible very easily with the help of centrifugal force. Simple centrifuges are used in chemistry, biology, and biochemistry for isolating and separating suspensions. They vary widely in speed and capacity. They usually comprise a rotor containing two, four, six, or many more numbered wells within which the samples, contained in centrifuge tubes, may be placed.
