With much advancement in technology, the world has become a smaller place. If it hadn’t been for immense efforts in scientific research, not much interesting information would have been available for the world. When it comes to experimenting with science, there are many things available in the laboratory. It is because of the sensitive scientific equipments that science has been able to dig deep into the crux of everything that humans want to know about. When going to the science laboratory, one of the most commonly used equipment is the centrifuge machine.
This machine is not just a part of the laboratory but also the need for the house. There are many different types of centrifuge machines available in the market. However, every science laboratory will choose one that is coherent with the research that is being done.
So how do centrifuges work?
The function of centrifuges is very simple and clear. A centrifuge machine is responsible for separating solid from liquid or just two materials that have different densities. A centrifuge is of great help when scientists need to separate solid particles from an already dissolved solution. If it wouldn’t have been for centrifuge machines in the real world, very lesser would have been known about the solids and liquids. The most common myth that hunts centrifuge machines is that you need a centrifugal force to make them work. This is incorrect.
The functioning of a centrifugal machine is very simple, and it relies on the sedimentation principle. So basically, the acceleration of the rotor causes a centripetal force to put pressure on the centrifuge tubes. In this way, the smaller particles travel towards the center of the machine. The large particles are also known for getting stuck in the bottom of the machine during the process. These particles are known as pellets. The solution that comes out after the process is acknowledged as supernatant.
What are the common uses of the centrifuge?
Centrifuges are used for several applications. This is because there is a diversity in the centrifuge machines these days. Some of the most common ones are:
· Separation of wastewater sludge
· Isotope separation
· Separation of mixtures with close densities
· Separation of blood
· Separating creams
· Sediment suspended solids
· Material synthesis in a high gravity environment
· Washing machine spin function
These were just some of the common uses of centrifuges; there are many more.
What types of centrifuge are there?
There are several types of centrifuge available in the market. The only two qualities that people look for are the centrifuge size and the rotor speed. The most common type of centrifuge that people know about is the laboratory centrifuges. The one used in the laboratory is of the standard size and has all the properties that have been listed above. Regular centrifuges that you come across are the normal ones that are available in most of the laboratories. However, regular centrifuges are very important when it comes to treating DNA, viruses, antibodies, and proteins.
However, if there is less space in the centrifuge machine, a benchtop ultracentrifuge can be incorporated with the machine. However, conventional centrifuge machines can only hold light stuff on the top, so they are best used where the sample quantity is relatively small.
What are the types of rotor available?
The quality and speed of the rotor both have a direct impact on the centrifugation process. Rotors are made from plastic, metal, and composite material. The three main types of rotors are drum rotors, fixed-angle rotors, and swing-bucket rotors. The rotor with the maximum speed is the one that people are usually trying to hunt down because it can speed up the entire process.
Centrifuges are used all over the world because of their important benefits.
