What should be considered when purchasing centrifuge tubes

There are many factors to consider when purchasing centrifuge tubes. The performance of pipes varies, and you can decide which factors can meet your needs. Here are some precautions when choosing a centrifuge tube.
Chemical resistance
When discussing the resistance of pipes to certain chemicals, the type of material is important. You should definitely consider which chemical you are using and ensure that the tubing can withstand this substance.
Polypropylene (PP) is a popular material because it can withstand high speeds and is resistant to most organic solvents. However, it is still a good idea to check the resistance of the PP pipe before use.
Relative centrifugal force
The maximum speed at which a centrifuge tube can rotate. There is a significant difference in the speed that each brand can withstand, which is why choosing the right pipe is crucial.
Check the relative centrifugal force (RCF) to determine the speed at which a specific tube can be rotated. RCF is the gravity applied when operating a centrifuge. RCF can affect the pricing of centrifugal tubes.
This sounds like rotational speed per minute (RPM) is a feature that you will consider when deciding which pipe to purchase. But RPM only measures rotor speed. Excessive gravity can damage unsuitable pipes.
When purchasing pipes, it is easier to budget if you first understand the RCF speed you need. If you are not working at high speed, you can purchase a centrifugal tube with a lower RCF rating
Glass VS plastic
Glass may be a better choice to ensure that you use sterile test tubes, as this material is easier to clean afterwards. Plastic is not difficult to clean, but it is more difficult to disinfect. Glass is also a safer alternative to corrosive metals. Glass centrifuge tubes are rare.
Glass can better withstand higher temperatures, but it also has drawbacks compared to plastic. Plastic is more durable and cheaper. You cannot find a glass tube that is small enough for a micro centrifuge.
capacity
When purchasing a centrifuge tube, the final consideration is how much you need to fill. Most of the time, you only fill three-quarters of the centrifuge tube. Overfilling the pipe can cause leakage.
The overspeed centrifuge tube is an exception. These centrifuges rotate at very high speeds and require filling the pipes to the top to avoid collapse. You must also be careful not to fill insufficient pipes.
