The centrifuge works under the influence of gravitational force, using the code of sedimentation. The material is separated by density, as the central acceleration causes the separation and movement of materials and molecules. Where the less dense materials are displaced and move to the center, thicker materials settle in a deposit at the bottom of the tube.
The low-density material rises, and it mentions different types of separation, most notably coking. In which particles are concentrated in the form of granules at the bottom of the centrifuge tube and then begin separation processes from the solution, excess substances remain floating.
During this process, chemicals transform from a basic or water medium into a solvent, and some protocols identify centrifuge forces, acceleration, and rotation in centrifuges.
What Is A Centrifuge?
It is a device used to separate mixtures using centrifuge force, where the centrifuge operates by an electric motor that rotates in rotational motion around a fixed axis.
The centrifuge also works by placing the body in a state of rotation around a fixed axis, applying perpendicular force to the axis of rotation outwards.
Centrifuges consist of essential components, as follows:
Rotor: it is the part that carries pipes, bottles, or bags containing centrifuge fluids; there are different sizes and types of rotors, which are interchangeable with each other.
Driving column: the connecting part between the engine and the rotor. Machine: the motor provides the ability to rotate the rotor in the device.
Cabinet: surrounds all parts of the centrifuge, protects the device in the event of a crack or broken pipe, as the operating controls, speed, and time indicators on the cabinet.
Brakes: most centrifuges have a brake system to stop the rotor after the operation, and these brakes are electric and not manual.
Tips For Choosing The Suitable Centrifuge
Centrifuges have been available for many years, especially in laboratories. Still, many have questions about the type of centrifuges ideal for their needs, and to help choose the most suitable device, it is preferable to take into account 5 points at the time of selection, as follows:
Speed: The device’s speed is a critical point for selecting the centrifuge, where the rotation speed measure by unit (RPMs). And to ensure the correct selection of the centrifuge, you must know the rates required for tests in separation processes and materials used in the laboratory.
Flexibility: the flexibility of the device is vital in searching for a suitable centrifuge, as the user may need to switch device rotors to suit its uses. Which may change over time.
Ease: it’s best to choose an easy-to-use centrifuge, i.e., you don’t have to choose a complex device. But a machine that everyone can work on, turn on, and off without complications. And also, has an easy-to-navigate control panel.
Use apps: find a suitable device by downloading some unique apps available for free in app stores, as the user can search and choose what suits them among the many existing choices.
What Is A Centrifuge Technique?
It is a technique that helps separate mixtures by applying centrifuge power to materials. The Particles separate from the solution according to their size, density, shape, rotor speed, and middle viscosity services.
High-density particles in the solution descend. And also, light floats up. The more significant the difference in density. The faster the material moves since if there is no difference in thickness. And also, the physicality remains constant.
The gravitational force can replace by the centrifuge force provided by the device to take advantage of minor differences in density. Many factors affect centrifuge technology. Most notably: density of samples and solution. Viscosity. Temperature. Particle displacement distance. Rotational speed.
Uses of it
Centrifuges of all kinds are used based on rotational speed in many applications in everyday life, including high-speed centrifuges used to separate particles and atoms. Where a gas centrifuge is used in uranium enrichment experiments.
Separating different isotopes. The uses of centrifuges are in various factories. Where it use to separate butter and cream from milk and pour minerals. And also, prepare chemicals.
We use them as washing machines to separate water from clothes. Which drains them, and in some kitchen utensils used to wash vegetables. Wah the vegetables and then squeezed with the same Principle as the washing machine. Moreover, Nasa uses the centrifuge to simulate the significant push of astronauts into their seats as the rocket moves into space. Preparing them for what they may face during their journey.
We use Centrifuges in medical laboratories to prepare blood samples for analysis. Especially when blood components need to separate from plasma, red blood cells. And also, other details, split depending on their density variation.
The bottom line is that we use centrifuge is mainly to separate mixtures based on their density and follow sedimentation principles. The separation process influence by the thickness of samples, temperature. And also, other factors.
Therefore, You should note that many applications are using the centrifuge, including dairy factories, cheeses and their derivatives, medical laboratories. As well as in space agencies and the nuclear weapons industry because of its benefits. And also, facilities in the separation process do not exist in other devices and machines.
