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.

Centrifuge Cleaning Tips to Ensure An Efficient Centrifuge

A centrifuge device is quite in many laboratories. In fact, most of the hospitals and other chemical & biological laboratories cannot do without one. This is device has many applications and high usage. The way the device works is that it spins the sample which is likely to be a fluid sample at high speeds. It often happens that there are spills and hence it is necessary to make sure that the device is kept clean. In addition to which the centrifuge is also used for toxic samples hence this makes it more important that the centrifuge is clear of any foreign particles. Thus centrifuge cleaning is important and here are a few tips to help with the centrifuge cleaning procedure.

Maintenance tips for Centrifuge device:

  • The outside of the centrifuge can be cleaned with a soft cloth and should be done gently. It is permissible to use mild soap or even a commercial soap product along with water to wipe it clean.
  • It is recommended one uses a domestic cleaner with pH 6 or pH 8 for the general cleaning of the lid and case as well as control panel of the centrifuge.
  • The inside of a centrifuge is not always manufactured from the same material. The material used inside the centrifuge can either be plastic, ceramic, aluminium or stainless steel. Hence while bleach may be good for one of the surfaces it is not good for stainless steel surface. Hence the safest way to ensure the inside of the centrifuge is kept clean is to check the manual for the centrifuge which should clearly state what to use.
  • In case a radioactive sample has been used, it is possible to use a solution with 70% ethanol and 10% sodium dodecyl sulphate in water. The parts can be rinsed in ethanol first and then de-ionized with water.
  • Some of the centrifuges make the job of maintenance easier. This is because some centrifuge devices have a system called ‘Clean in place’ (CIP). This system can effectively the parts of the centrifuge automatically.
  • The build of moisture inside the centrifuge should be prevented by taking proper steps and cleaning or wiping are regular intervals.
  • Some of the centrifuge devices have a vacuum system. This system is often found on the high speed centrifuge devices. Such devices will always have a rubber seal too. To ensure proper operation, it is vital that these rubber seals are kept clean.
  • Besides which there are other centrifuges devices which also have fans and refrigeration. Such device are likely to have an air filter. It is vital the air filter on such devices be kept clean.

Important factors to be aware off during maintenance of centrifuge:

  • A centrifuge device can have a temperature feature and hence it would have an optical sensor or a temperature sensor within the bowl. These sensors can be very sensitive and hence utmost care is required while cleaning them.
  • For a centrifuge that spins at a very high speed it is very important that it be placed on a level surface. Furthermore, the centrifuge device is likely to have stoppers underneath which can come lose or detached while cleaning. It is thus important to ensure that they are firmly fitted after completing the maintenance procedure.

Scheduling Maintenance & getting professional help:

It is a good idea to schedule the regular maintenance of your centrifuge device. This way you can be sure that the device ready to use when you need it.

The maintenance is something that can either be done by yourself or by taking help of the professionals. However, there are some situations in which you should always take help from the professionals as listed here.

  • In case of unusual sounds like knocking or scraping or grinding noise it is a good idea to call in the professionals for a closer inspection of the device.
  • The centrifuge devices can be quite sensitive. Hence in case of a spill or a leak it is at times hard to remove the spilled sample. In such cases it is also a good idea to call in the professionals.

Function and Uses of a Medical Centrifuge

iFuge D06

A centrifuge is an instrument that makes use of the principle of centrifugal force. The basis centrifugal force lies in how the force is being applied. Centrifugal force is essentially an outword pusing force that is felt by bodies moving in a circular motion. As you may have noticed I mentioned the force is felt by the bodies and not applied because there is no direct force being applied in the outward direction. Hence it is also often referred to as a fictitious force.

This force that is felt by the bodies in circular motion is due to the inertia and inward pushing exteranal forace. The centrifugal device makes use of this theory while spinning samples at high speeds.

Applications of a Medical Centrifuge:

A Centrifuge is found in almost every medical laboratory, be it a hospital, a research laboratory or a private practice. This is a versatile, efficient and extensivley used device with some it’s applications mentioned here:

  • Blood Sample Separation: A centrifuge uses small samples of liquid in the form of tube samples to process. It is capable of separating blood samples into upper plasma layer, a thin interface layer consisting of white blood cells and platelets as well as a lower layer consisteing of red blood cells.

  • DNA/ RNA Separation: This is a two step process which involves spinning the sample at top speed for a short while and later carrying out the second step in the laboratory using chemcials.

  • Cell Culture Separation: The process of cell culture separation is possible by using a sample in conical tubes. This process is possible with the help of a centrifuge.

  • Others: There are several other applications of a medical centrifuge that includes study of viruses, proteins, nucleic acids, polymers and blood . There are also several other centrifuge devices besides the medical centgrifuge that can be used for many different applicatoins like in the petroleum industry as well as cosmetic industry.

Features:

A medical centrifuge is a simple device that spins samples in a tube.” This is a vage description of a centrifuge. However a centrifuge is much more that just a simple device and hence has several good and useful features that you can take advantage off:

  • Cooled Samples: There is the option of going for the refrigerated centrifuge device which has the ability to keep the samples cool and in a state that preserves the sample.

  • Size: The centrifuge is available in several sizes which at times also depends on the power of the device. A device with high RPM will generally be heavier and larger. A centrifuge needs to be placed on a very sturdy table so that there are movements due to the virartions it

generates. Hence a portable centrifuge will ideally be a small one with low power.

  • Others: A centrifuge has several other features and funcitons that can make it easier, safer and more effecient. For example an autopmatic lid lock can avoid a big mess in terms of spills due to a lose tube or unsecured tube.. At the same time an auto shut down feature when the lid is openned is also a good safety feature that can prevent accidents. Many of the devices have varying speed levels and are also programmable thus adding to the number of appilcations.

The perfect Medical Centrifuge

iFuge D06

Of all the medical equipment found in medical laboratories, the Medical Centrifuge is one of the most common one. Almost all laboratories will have a requirement for a centrifuge, be it in a hospital, a medical laboratory or a private practice of some kind. Since this device is so much in demand, it is necessary to be careful while making the purchase so that you do not end up with the wrong or defective one.

Here are a few factors that are listed that you should take into consideration while obtaining a good medical Centrifuge.

Application:

The centrifuge is mainly sued to separate solid from liquid suspension and thus has many applications like:

  • Science and Medical laboratories to separate proteins and chemicals.
  • For several non-hazardous substances like urine or blood.
  • Blood banks usually require high speed centrifuge
  • Pharmaceutical companies also make use of it
  • The Petroleum industry also makes use of a centrifuge, although it is different from the medical centrifuges used for medical purpose.
  • The sugar industry uses it to separate sugar from liquor too.
  • Life Science and testing laboratories.

Hence it becomes essential to make some knowledge of the type of the centrifuge that you require. The main factors to look our for are:

Spin Speed:

Hence it becomes essential to have some knowledge of the type of the centrifuge that you require. Special importance needs to be given to the speed of the centrifuge, since that is the main factor in a centrifuge. The revolutions per minute tend to vary from device to device. The main factors to look our for are:

  • What you need to spin?

  • The speed at which you need to spin it.

  • How long do you need to spin it?

  • The programmable flexibility.

  • Being able to pre-program the speed settings.

  • Do the settings give you precise control?

Size:

But that is not all, a centrifuge is available in several sizes as well. Size is important, depending on the application and also on how much space you have in the laboratory. The reason being that a centrifuge should ideally be placed clear of other disturbances, in a clear spot which does not vibrate and is not unstable. The device is capable of spinning at high speeds and the higher the RPM, the heavier the device (in general). Thus medical laboratories can afford to invest in a big one which is slightly heavy however since they will rarely be shifting it around. On the other hand if you require it to be portable, it would be wise to select a lower power one which is likely to be lighter.

Construction:

The medical centrifuge being a very handy device is likely to be used several times a day, if not constantly. Hence it is necessary to select a good quality one that does not break down easily and at the same time has low maintenance as well.

Additional Features:

A medical centrifuge can come with several extra features and options that may require and can choose to include:

  • Keeping it cold: A refrigerated centrifuge as the name suggests can keep the contents cool. This is often required for certain samples. For example while running tests on blood, it is often vital to maintain the low temperature are which blood is stored.

  • Automatic lid lock: This makes sure that when the centrifuge is operational the lid locks automatically and hence if you do happen to attempt to open the lid it will not open. Additionally it is also necessary that if the lid does open for some reason while the centrifuge is operational it should shut down instantly.

Conclusion:

The right centrifuge can make your day, while the wrong can set you back a month or two. Hence it pays to have some additional information about the device. Neuation Technoligies provides next generation laboratory equipment and also follows the ISO 9001 & USI 13485 standards. They are medical equipment manufacturers. Thus the benefit of picking one of the many centrifuge devices that they have to offer is that you can be certain that it is a feature rich, good quality device that has been built tough.

10 tips to use Doctor’s centrifuges safely

Doctor's centrifuges

Doctor Centrifuge is a very common laboratory equipment, in addition to which it is also a vital piece of research equipment. This device operates at a very high speed, and it is for this reason that it is effective in separating the material based on density. This same high speed can also be a hazard at times, resulting in aerosol creation to equipment instability and failure. In case the centrifuge tube breaks inside the rotor, Aerosols is created inside the centrifuge. There are several other hazards like the instability within the equipment due the unbalanced rotor can be quite hazardous at those high operating speeds and cause injury and damage in a laboratory.

Thus it becomes very important to use the Centrifuge device safely since if the rotor does fail due to excessive mechanical stress caused at high rotational speed this can also result in flying metal fragments that can very easily injure the laboratory operator and damage the laboratory itself. Here are a few tips that should ideally be followed:

  • Make sure that the centrifuge bowls and tubes are dry prior to use, this is in fact quite important as well.
    Another factor to consider, especially when having multiple centrifuge devices is to match the set of tubes, buckets and other equipment to make sure they are of the correct specification.
  • Any material used along with the centrifuge should first be inspected thoroughly. For example the sample tubes should be inspected prior to use and if you notice a crack of some kind it should not be used under any circumstances.
    It is a good idea to make use of the centrifuge safety cups provided to prevent aerosol spills of potentially infectious materials.
  • There may be situations when a spill may occur and the sample tube material is infectious. In such a case it is advisable to wait for 10 minutes after the rotor has stopped before opening the lid of the centrifuge.
  • Over filling the samples tubes can also be one of the reasons for spills within the centrifuge device and thus it is best to avoid that.
  • Make sure the surface the centrifuge is placed on is flat and even so that there are no vibrations when the device is in use.
    In the case where you do notice some wobbling or shaking of the centrifuge while it is operational, it is necessary to pull the plug immediately. Failing to do so can damage the device and even cause injury.
  • One thing that the laboratory operator should always remember is to take special use while preparing the Centrifuge for use. The number of tubes in the rotor should always be even in order to balance the rotor. As an example if the sample being used in the centrifuge is of 15ml then a 15ml tube of water should b placed in the opposite section to balance the rotor. The density of the sample also needs to be taken into consideration. Thus the total mass of the tubes on both the sides should be similar. This is important since the centrifuge spins at a very high speed and any imbalance case permanently damage the centrifuge and has also the potential to cause injury to the operator.
  • It is important to follow the practice of correctly labelling the samples present in the laboratory. Though this does not affect the centrifuge directly since the centrifuge doesn’t really care for the labels, it is quite helpful within the laboratory itself. By labelling the tubes, the laboratory personnel are always aware of the contents of the tube and thus it is hard to mistake it for something else. In the case where the sample tube does contain a hazardous substance, the laboratory personnel will not be in the dark about the content and thus can handle the tube in an appropriate manner.

Conclusion:

Thus it is very easy for things to go wrong even when using a relatively simple device like a centrifuge. Thus ideally it is safe for only proper and trained laboratory technicians to use this device. But even the technicians do over look some of the basic safety features at times and pay the price. The tips mentioned here are very useful for preventing such incidents from happening. This is a fairly big list of important points to keep in mind while using a centrifuge device though not the complete list of factors. For example it is also not advisable to open the lid of the rotor whilst it is motion and it is also a good practice to wear safety goggles while working with a centrifuge device. However the main safety issues have been mentioned here and should always be taken into consideration while using a centrifuge device.

Neuation is one company all but aware of the importance of safety in Centrifuges. They have a wide range Centrifuges devices that have many different functions available as per the needs of the institutes. One thing that Neuation makes sure of is that their devices work well at high speeds and that they are also safe. They lay extra stress on the safety features of the devices.

A short note on the caring for your Medical Centrifuge

iFuge D06

A Medical Centrifuge is an instrument that spins samples at a very high speed. This forces the heavier particles to collect at the bottom of the tube. For example a Medical Centrifuge is extensively used for separating the cellular components of blood from the liquid so the liquid can be used for testing. The Medical Centrifuges vary in size, capacity and speed capability. Medical Centrifuges usually have a speed capacity of 0 – 2000 rpm and are capable of holding tubes ranging in size from 5 ml to 50 ml. The medical centrifuge used in the blood bank are often called serofuge and spin tubes with capacity of approximately 2 ml to 3 ml.

Maintenance of a Centrifuge:

Like every other medical instrument even the Medical Centrifuge requires regular maintenance. In addition to maintenance of the medical equipment, it is essential to also care for device after every use. Here are a few tips for maintenance:

  • The initial calibration of a centrifuge should always be performed by a qualified service technician.

  • In an ideal world the maintenance procedure should be carried out on a daily, monthly or annual basis.

  • One thing that should be followed to prolong the life of your centrifuge is to wipe the inside to the bowl with a disinfectant solution and rinse it thoroughly immediately after use.

  • To prevent from causing damage to the centrifuge it is a good idea never to use it when it is hot.

  • Things to look out for when the Centrifuge is in use is unusual vibrations, or noise, as well as deterioration of parts. When such cases are noticed it is advisable to stop the centrifuge device and remove the plug. In addition to this it is advisable to contact a qualified service technician.

  • In addition to cleaning the device after use it is also essential to have a monthly maintenance routine for your medical centrifuge. There are a number of things to include in your monthly routine like cleaning of the centrifuge housing, rotor accessories with a neutral cleaning agent. Typically the centrifuge device should be cleaned with a mild cleaning agent.

  • The monthly maintenance should be complemented with an annual maintenance. The ideal person to do this would be a qualified service technician.

  • The annual maintenance should include the cleaning of condenser coils, filter as well as the fan screens. The centrifuge brushes should be checked along with the bearings, timer, temperature and speed as well the electrical integrity.

  • There is a nut that secures the rotor to the shaft, make sure that this is not lose.

Repairs and fixes of a centrifuge:

There are several cases when you may need to repair or fix the medical centrifuge. If you are a laboratory technician then you must be more than familiar with spills and minor accidents that occasionally do occur. Here are few common issues and their fixes:

  • It often happens that during the operation of a centrifuge liquid from the tube spills on the centrifuge device. Such spills should not be ignored and should be cleaned immediately. The reason being that such spills can easily cause corrosion or damage.

  • The tubes used in the centrifuge do not last forever. They develop cracks over time. Using a tube which is cracked is extremely dangerous especially when using hazardous substances. These tubes can easily break while inside a centrifuge and cause a lot of damage. Thus such tubes should be replaced as soon you come across them.
