# Uses of Centrifuge

## Introduction

Centrifuge and its application explained by Sir Isaac Newton in his second law of motion. He outlined that a moving body when it is free, travels in a straight line. The opposite in his theory is the restraining force when it changes its position. This force generally exerts pressure against the restraining force so that it can travel in a straight line. The theory about it is that the force extends by extending the angular velocity of rotation and the mass of the object. The centrifugal force sometimes connected straight with the pull of gravity of the object.

## What is Centrifuge?

Centrifuge is the mechanism, which works with centrifugal force. This are extracted from the separation of liquid of the mixture. Under this mechanism, the heavy part of the substance drifted away from the axis. The lighter part of the substance is slightly shifts towards the axis.

This mechanism of centrifugation has many uses like, collection of cells, and taking part in DNA. In this process when spins quickly the lighter particles flow at the top and the heavier particles sets at the base level. Centrifugation is the mechanism, which extracts the liquid by the use of centrifugal force, basically there are two types of centrifugal force such as different centrifugation and centrifugation of density gradient.

## Types of Centrifuges

There are various types of centrifuges such as −

### Bottle Centrifuges

This is a type of batch separator which is used for testing and control. This area also has many uses such as taking part in the separation of test tube or in bottle type container which is attached to a vertical shaft. It is used for biological, chemical and medical laboratories. Most of the bottle centrifuges have quality material used in biology, chemistry and medical laboratories. These obtained in the purification of liquids and by the process of extraction of solid particles.

### Tubular Centrifuges

It is the process of extracting the liquids from liquids sometimes this gets incomplete and the extracted part is processed in the machines for a couple of times. This Tubular Centrifuge is extending in terms of its number due to its high centrifugal fields. These high centrifugal fields being used for several purposes like filtration of vaccines, filtration of lubricating and oils, cleansing the food items. In many industries, this is used in cleansing immiscible liquids.

### Disk-type Centrifuges

This is composed of a vertical stalk of disk. Its mechanism of sedimentation performs in a radial direction which has the gap in between the cones. This decreases the distance of the Settling by which the speed of material separation increases. This is also used in the filtration of fuel oil, recycling the used motor oil and it performs in cleansing the vegetable oil.

These are a part of centrifugal filters. This is composed of a cylindrical tubular rotor. Sometimes the external wall consists of good mesh screens. In Basket centrifuges, the liquid gets through the screen where the substances are deposited. This performs in the production of sugars and for commercial purposes like drying of clothes and much more.

### Vacuum-type Centrifuges

This type of centrifuges is used in finding the molecular mass of every element that is available in the solutions. In the modern world, this is considered an important technology as it this highly reliable and can be used in the electric motor drive.

This has helped in the redesigning of machines which are used daily.

## Uses of Centrifuge

Some important uses of Centrifuge are as follows −

• Dewatering is the process of centrifuges which lowers the bad smells if this is done conventionally.

• This thing is very much portable when this is deals with oily substances.

• The centrifugation is not very costly.

• This is considering being the automated process.

• This has mechanisms for heavy purposes as it has a great build quality.

• This has the mechanical safety working functions, which are composed of good materials. It consists of some sensors which has great reliability in terms of production.

• This is simple to use and is composed of microcomputers which restore settings for rotational speeds and centrifugal force.

• Due to the extended use of dry solids for silts then is the best choice for filtration by the use of Centrifuges.

## Conclusion

Centrifuge is a device, which consists of a force known as Centrifugal force. This consists of a force which is stronger due to the presence of gravity. The centrifugal force sometimes is sometimes is connected straight with the pull of gravity of the object. This is denoted by gravity.

In this process when spins quickly the lighter particles flow at the top and the heavier particles sets at the base level. This is considered an important technology as it this highly reliable in industrial and its production purpose.

## FAQs

Q1. What is Centrifugal Force?

Ans. Centrifugation is the mechanism, which extracts the liquid by the use of centrifugal force. There are two types of centrifugal force such as, different centrifugation and centrifugation of density gradient. This is the upward force on a weight of an object when it is rotated.

Q2. What are the uses of Centrifuge?

Ans. One of the major uses of centrifuge is that, can be used for heavy-duty as it has a great build quality. This is also used in the extraction of fluids, liquids, gases in terms of their densities.

Q3. What are the types of Centrifuge?

Ans. In centrifuge, many types of centrifuge are micro and table-top centrifuge. Some other classifications of it are swinging bucket rotors and fixed-angle rotors.
