Centrifuges are an indispensable tool in many laboratories that require separations based on density. These instruments spin samples at high speeds, driving heavier components to the bottom and lighter ones to the top. While centrifuges are generally reliable, they can develop issues that prevent proper operation. This article explores common problems that arise with centrifuges and provides tips for troubleshooting them to ensure that your research proceeds smoothly.
Start-Up Failure
One of the most common issues with centrifuges is that they do not start up. In some cases, this could be a simple fix like ensuring the power cord is properly connected. Before making any assumptions, it is always best to check the easy fixes first. Another point to note is age. If the centrifuge is quite old, it may need a replacement. A spinning centrifuge is a very dangerous hazard, and safety should always be the main priority.

Excessive Noise/vibration
It is common to observe excess noise or vibration from the centrifuge. These usually indicate balance issues. If you detect unusual vibrations in your centrifuge, check the balance of the rotor. Ensure that the centrifuge is level and well balanced with the rotor offering no deformations or abnormalities. In addition, ensure there is no physical damage or wear to the machine.
Overheating
Symptoms of overheating include an error message, smoke, scent, high temperature, and machine shutdown. Overheating centrifuges usually have faulty components that require repair or replacement. Ensure that the centrifuge is at maximum rotor capacity, within the specified RPM range, and the sample is cold before spinning to avoid overheating.
Leaking
If a centrifuge is working but you notice, you have a liquid leak; it is essential to stop the centrifuge immediately to avoid endangering yourself and others. Most likely, the problem is a damaged tube, broken seal, or overfilled sample. Leaking samples can easily compromise spin results and create a mess besides. Before any spin, it is always important to check tube-gasket compatibility and orientation.
Unbalanced Rotation
Centrifugation usually involves spinning, but when there is a wobbly rotation, it could indicate a balance issue. This could be a result of bad rotor bearings, ball joints, spindle assemblies, or other mechanical causes. Ensure that the tub is well loaded in a balanced manner, and the rotor is clean and well attached. It is always good practice to slowly increase the RPM rather than spinning at maximum RPM.
Closing Words
Centrifuges are valuable tools that require proper care and maintenance to ensure they perform optimally, give accurate results and remain safe to use. Troubleshooting centrifuges can be a challenging task, but with this guide, you are better equipped to handle any arising issue. Always contact a professional if the severity of the problem is unmanageable. Proper calibration and periodic maintenance will enhance the longevity of the centrifuge.
