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

Tubes

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.

Equipment

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.

Rotor

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.
