Centrifuge – The most popular Laboratory device

A centrifuge is one of the most popular laboratory devices around. Almost every chemical and medical laboratory will have one, besides which several other laboratories also have a centrifuge. The Laboratory Centrifuge There are many applications of a centrifuge device. It has medical applications like helps in the analysis of blood, it has chemical applications, like help in the analysis of several chemicals. A centrifuge is also used space station laboratories for testing purposes. A laboratory centrifuge is a device that is driven by a motor that spins the liquid sample at a very high speed. The size of the centrifuge can vary, depending on the size of the sample. Such centrifuges come with a speed setting as well. The basic principal of a centrifuge is the sedimentation effect, where centripetal acceleration is used to separate greater and lesser density substances.

What is a centrifuge used for in a lab?

What is a centrifuge

A centrifuge is a very useful device in the laboratory. There are many applications for this device. It is used in the separation of fluids, gas and other liquids based on their respective density. The way it works is by spinning the sample at a very high speed in the centrifuge and allowing the centripetal force to separate the heavier particles to the outer section of the centrifuge. Here is a list of applications of a centrifuge in a laboratory:

  • The centrifuge is used to separate a blood sample into different components. This separation helps in the analysis of the various components of blood like, red blood cells, white blood cells, plasma, etc.
  • A centrifuge is used in DNA / RNA separation. It is also used for cell culture separation.
  • Besides which it is also used in the study of viruses, proteins, nucleic acids, polymers, and blood.

What Are A Centrifuge And The Theory Behind It

A centrifuge is basically a machine that spins around to create a force. It has many practical purposes like to separate blood products which help in the analysis of the blood. It also has many other practical applications in aerospace labs where huge centrifuges are used for testing the endurance of space equipment.

How do Centrifuges Work?How do Centrifuges Work?

A centrifuge works on the basic principle of the force that is generated when you spin something. For example, when sitting in a merry go round while spinning at high speed you will feel a force that hurls you out of your seats but you still remain in your seat. This is an invisible force and is also the basis of how a centrifuge works. The fact of the matter is that this invisible force so to speak is called centripetal force. The basic principle behind the working of a centrifuge is the fact that denser substances and particles move towards the outward direction due to the centripetal acceleration. This also causes the less dense objects to move the center. The centripetal force is the force that acts on a moving body that is moving in a circular path and is directed towards the center of the body in motion.

What do Centrifuges do?

Centrifuges are used for scientific purposes in several chemical laboratories. It is thus possible to separate red blood cells suspended in blood plasma. Thus if a test-tube with a blood sample is placed in a centrifuge, you will find that the plasma is suspended at the top and the red blood cells at the bottom. What are centrifuges used for? Centrifuges are commonly used chemical and medical laboratories around the world. It has the ability to spin the sample at high speeds. A sample is usually placed inside the centrifuge with a tight latch to keep the lid in place. When in operation, this device spins at high speeds causing vibration and at times can be displaced by the force too. Hence the centrifuge needs to be placed in a sturdy place.

Definition and Functioning of Clinical Centrifuge

Clinical Centrifuge Definition

Clinical centrifuge machines are the most basic machineries in any clinic. These equipment are used to test liquid found inside the living being. It separates plasma from the blood. It rotates on the axis on fixed density, sometimes 1500 RPM in one minute. The timer button is given on the equipment. The person who is performing the test sets the timer as per the test requirement.

Basically, how does clinical centrifuge functions?

It is a small equipment, and can be found in any biotechnology school and college lab. This machine is fixed on the axis which rotates in high speed in the same location and in the same speed. The laboratory person inserts the liquid in the tube and places a cap on it. The tubes can be of either plastic or glass. The capacity of the tubes vary from 10 ml to 100 ml. Then he or she inserts the tube in the equipment and shuts it. Timer is set with the required RPM. It works on the sedimentation principle where parts of water are separated (if you remember the chapter of sedimentation studied in the school). The same way particles are separated. The heavy density particles stays in the bottom and the light weighted comes up.

As per the need and requirement these following types of centrifuge can be used;

1. Micro Centrifuge
2. General purpose centrifuge
3. Large capacity
4. Super speed

Clinical Centrifuge UseDoctor Clinical Centrifuge

However, the type of fluid separation depends up on the density. And the density is determined by the type of centrifuge. When we say separation it means, separating plasma from the blood, protein from the fluid, other solid particles from the fluid. It also separates sediments from the urine. Such tests determine the type of disease in the living being.

Beside, density and timer there is a button called temperature. Different different tests require varied temperature, some require less and some require high.

These are the most common tests happen in the clinical centrifuge laboratory. It was earlier used to separate DNA from the blood, but now there are more advance technologies available for separating the DNA, and thus it is less popular in the centrifuge lab.

Training of Operation

The equipment comes with in-build safeguards. It is recommended to the laboratory operators to clean all the equipment in the lab twice a year.

Balancing of tubes is very important during the run. Make sure all the tubes are placed in front of each other to avoid unbalancing.

If, in case, equipment require extensive and frequent services, it is better to replace.

Everything That You Need To Know About Micro-Centrifuge Equipment

What is Micro-centrifuge?Microcentrifuges

They are same as the Centrifuge, the only thing is that they carry lesser amount of fluid to test-maximum 2 ml or lesser than that. The liquid samples inserted in the tube spin at a very high speed.

So, what does a micro-centrifuge do?

The main reason they are used is to centrifuge nucleic acid and protein. When we say nucleic acid and protein, it means DNA and RNA. These tests are run in molecule laboratory. Amongst other clinical laboratory it is used excessively in molecule biology section. The samples tested here are very small in quantity, but the big research depends on these quantity only. These tests are performed using Eppendorf tubes. These tubes are specifically made for molecular labs only. These tubes are used in PCR laboratories as well.

Understanding Functions


The tubes inserted in the equipment are small in size. They are built up of plastic, and they are supposed to discard after one use. They are cylindrical in shape. The tubes have different sizes as per the fluid quantity. They come in 0.5 ml, 1.5 ml, 0.2 ml and 2 ml size. The most common tube size is 1.5ml. Disinfection of the tube is possible, but due to small size they are difficult to clean, but inexpensive. So it is better to purchase new one.


The maximum speed of this equipment is 13000 to 15000 RPM (round per minute). The equipment has a button that allows you to set the speed. Alike, centrifuge equipment the balancing of tubes is important-technically it is called sample loading balancing. By balancing we also mean that the quantity we are inserting in one tube should be similar in remaining tubes. Which means if one tube has 1.5 ml fluid, other tubes must consist around same quantity. Sometimes it is seen that the laboratory person has only one sample to test. In that case he can insert water or oil of the same density of the sample in other tubes and run the test.


There are two types of rotor;

  • Fixed Angle Rotor
  • Swinging Bucket Rotor

The rotor lids come in two types, one is plastic which is helpful in avoiding corrosions and are transparent. Second is built up of steel which is easy to use and much safer. Both have their own advantages, however, metal rotor lids are recommended.

Safety Measures

Sometimes during the test, the equipment starts vibrating. To avoid such cases try to keep surface in level.

A Guide to Help by the Appropriate Microcentrifuge

Medical-CentrifugeAll most every medical laboratory will have a Microcentrifuge device; the main reason being that there are many uses of Microcentrifuge device. It is very common for a chemical and biological laboratory to have one too. This is one device that is used to a great extent in such labs and for many other applications as well.

Since a Microcentrifuge is so commonly used, there are several types of them available. This article goes on to explain the subtle differences and special choices that you can make when need to buy centrifuge.

The Tube:

A Microcentrifuge can be used with a wide range of tubes. The tubes are usually special purpose ones and then there are also those for general purpose.

Here are a few tips that may come handy when selecting a tube:

  • It is important to first make a note of the type of samples that will be used with the microcentrifuge, since different samples have different requirements.
  • The tubes themselves can be straight or curved walled. They can also be with screw tops or pop tops.
  • Their size can also vary like 0.5ml or 0.4 ml or even 0.2 ml. These are the small sized tubes and will usually require an adapter to fit in the rotor’s holes.
  • The normal sized tubes can be like 5ml and even upto 50ml.
  • Furthermore, there are several other special purpose tubes ls, like cryotubes, HPLC tubes, PCR strips, mcrotiter plates and hematocrits also called capillary tubes.
  • The rotor essentially dictates the type of tube that can be used with the mircocentrifuge. However, you do have the option of switching between rotors in some microcentrifuge devices, but not all of them.

Rotor Specifications:

  • The capacity of the rotors also vary. The capacity of the rotors can range from 24, to 30 and evey 48 standard size tubes.
  • The rotors can also be special purpose ones to deal with the tubes that contain toxic substances. Rotors with special PTFE (Teflon) coating are available for high chemical resistance.
  • The other type of rotor is the swinging bucket rotor. This one is good for density gradient centrifugation and size separation.
  • The rotors also have a speed setting and different rotors have the ability to rotate at different speeds. Each rotor will usually have a rating which dictates the speed at which they can be rotated. There are also special safety settings that prevent the rotors from rotating any faster. For example, the 48 tube rotor has a lower rating than the 24 tube rotor.

How to Use a Magnetic Stirrer

How a Magnetic Stirrer can help you:Magnetic Stirrer

What is uses of magnetic stirrer? If there is one device that is very useful in daily tasks and yet not in the forefront, it is the Magnetic Stirrer. A magnetic stirrer has the ability to perform all the relevant tasks in the background while you go about taking care of the more pressing and important matters. The magnetic stirrer is essentially a small bar magnet and a stand which contains a rotating magnet. The bar magnet is usually in a plastic cover and a stand or a place has the rotating magnet. Thus this setup helps creates a rotating magnetic field.

The Magnetic Stirrer has several applications and is actively used in many different industries. The main tasks it performs is to either stir or mix fluid samples. This is very useful in the food industry and chemical industry; besides which it is also used in several other industries like biotechnology.

Uses of a Magnetic Stirrer:

A magnetic stirrer is often also known as magnetic stir plates. Several firms and people who often conduct chemical and biological experiments find these magnetic stirrer. If you have a requirement where the sample components need to be mixed a magnetic stirrer is the device for you. It is possible to use either liquids or solids samples to obtain a homogeneous liquid mixture. For example, the bacterial growth media is a kind of sample used in with the magnetic stirrer.

How to use your Magnetic Stirrer:Magnetic Stirrer

The way the Magnetic Stirrer works that an external magnetic field is applied to the magnetic stirrer mix solution. This happens when the sample that you have placed in the stirrer starts rotating with the small bar magnet. The magnetic stirrer is a fairly small device and hence it is very easy to use in a laboratory.

Benefits of using a Magnetic Stirrer:

A magnetic stirrer plays important role in minimizing the risk of contamination since there is only an inert magnet bar that is placed inside the sample (fluid). It is very easy to keep this device clean. A manual stirrer is different from the magnetic one. The magnetic stirrer is vital for the process of reproducible mixing or mixing for long period of time. In the case where you require the process of protein dialysis to be performed on a sample, you will be required to place the sample in the stirrer for a very long time. In fact many laboratories prefer overnight sample mixing thus enabling them to utilize valuable time. This would be possible only with a Magnetic Stirrer and not the manual kind.

Practical Magnetic Stirrers at Neuation make the difference:


There are many types of Magnetic Stirrer available like the heavy duty magnetic stirrer, the battery powered magnetic stirrer and even the air operated turbine magnetic stirrer. Each has unique characteristics and applications. Neuation is a company that design and develop their own high performance equipment with their highly skilled R & D team who make all the magic happen and constantly reinvent themselves.

There is More to Centrifuge Rotors That You Should be Aware Off

A centrifuge device can be found in several kinds of laboratories. It is quite commonly used in the field of medicine and hence all most every medical laboratory is likely to have one. It is capable of high speed rotation which is very useful in many areas of research.

The centrifuge rotation speed can be as high as 20,000 RPMs to even 40,000 RPM. In fact, it can also go as high as 100,000 RPM. The bioscience laboratories benefit a great deal due to the high speed centrifugation. The bioscience applications include concentrating cells in suspension, separating and isolating cell membranes from cytosolic contents and even purifying and isolating genetic material.

A centrifuge is not a device that is purchased very often and hence it is necessary to be aware of all the facts in order to make the right decision. There are several types of centrifuge rotors where all have a different application. Here are few facts that one should be aware off.

Tips & Facts Concerning Centrifuge Rotors:

Types of centrifuge rotors

  • The rotors can cost quite a bit; their price in terms of dollars range from 100 dollars to may be a few thousand dollars.
  • The cost of a rotor depends on the number of tubes capacity as well the size of the tubes, like either 500ml or 80ml, etc. In addition to which speed capabilities of the rotor also influence the cost.
  • Considering the fact that a good rotor, especially a high speed rotor with additional features can set you back quite large amount of money, it is advisable to make sure you give a good though to the current usages as well as future usages prior to selecting one.
  • It is important to note that the rotors do have a maximum speed specification and the higher the speed capability the higher the cost is likely to be.
  • It is necessary to be aware of the ‘k-factor’. The lower the value of the ‘k-factor’ the better and more efficient is the centrifuge device. A rotor having a lower ‘k-factor’ has the ability to perform its task faster as well. The ‘k-factor’ is based on the geometry of the rotor and the RPM as well.
  • The rotor design depends on the type vessel type being used. It is possible to use tubes, bottles as even microplates in a rotor. Hence if one has a clear picture of the future applications of the rotor and vessel type, it will help them in purchasing the correct one.
  • The centrifuge can be used for several kinds of samples. Some samples may need to be maintained at a low temperature, for example a blood sample, while other samples may be highly toxic. Hence special purpose centrifuges are also available with special purpose rotors.
  • The rotor material also plays an important role. It can be either metal, anodized aluminium or titanium.
  • The rotor configuration plays an important role in achieving efficiency. One of the more common configuration is the fixed angle rotor configuration. This configuration is usually used for pelleting cells.
  • The swinging bucket configuration is also quite popular. This has even spaced holes and the buckets are attached to the rotor by pivots. The buckets have the ability to swing outwards during operation.
