Centrifuge tubes are a very important lab apparatus used to separate different samples into their components. This is done by rotating these tubes rapidly around a fixed axis, which causes different elements in the sample to be easily separated. 

These tubes are essential in the lab and have a variety of uses. This blog will tell you all you need to know about centrifuge tubes. 

What Are The Top Uses Of Centrifuge Tubes?

  • Analysing Soil Samples

Soil can be extracted and analysed in a lot of ways. One of the methods is to mix it with water, causing the soil to cause the release of target analytes which can then be inspected. However, this is not a very effective method; the solution is quite muddy and murky, and the soil particles are too big to be analysed appropriately. A centrifuge tube to separate the contents is a worthwhile option in this case. 

  • Separating Blood Samples

Blood samples contain a lot of organelles and small molecules that need to be analysed and examined thoroughly for accurate results. All the components can easily be separated from the blood through centrifuging, and even viruses and other DNA or RNA can be isolated for further research and experimenting.

  • Isolating Process Samples

Many industries, such as the pharma and chemical ones, carry out a lot of processes combining water with other materials. Many of their samples contain many different contaminants, such as oil or fuel. For better water analysis, the sample needs to be centrifuged. After the elements are separated, the water can be collected through a pipette or syringe. 

How To Choose The Right Centrifuge Tube

Centrifugal Speed

All centrifuge tubes come with different tube ratings that the tubes can handle. Different kinds of tubes have various speed capacities; hence, it is crucial to determine your speed requirements and choose accordingly.

Volume

There are many sizes of centrifuge tubes available. It is important to note that a centrifuge tube should never be filled up to the brim. Overfilling may cause leakages and affect the accuracy of results. Centrifuge tubes are available in various sizes ranging from 15ml to 50 ml centrifuge tubes. 

It is advised that you keep centrifuge tubes of different volumes in the lab so that you may use whichever one is required according to the amounts of the reactants and substrates. 

Compatibility

Centrifuge tubes are made up of different materials, and their resistance varies accordingly. Depending on the type of chemicals and materials you choose for your experiments, it is crucial to select a centrifuge tube that can handle them. Some may be corrosive or poisonous and have the chance to ruin the tube.

We would advise centrifuge tubes made up of Polypropylene. It is pretty helpful for experiments involving high speeds, is autoclavable, and has a high resistance to most organic solvents. 

How To Use A Centrifuge Tube?

This is a quick and easy process. All you need to do is fill the tube with the sample you need to test and then cork it securely to avoid fluid leakage. After that, select the speed of the rotation and the number of times you need it to spin for proper separation. 

In the machine, place the centrifuge tubes on the opposite sides of each other. If you are dealing with an odd number of test tubes, put a tube filled with water to make the number even. Now you can start the rotation process. Once done, remove the tubes from the machine and place them in the racks for transportation and further experimentation.
