Common Centrifuge Problems and How to Fix Them

If you work in a laboratory or medical facility that has a centrifuge, you know how important it is for your daily operations. A centrifuge is a crucial laboratory equipment that separates fluids by applying a centrifugal force to the samples. A centrifuge works by spinning at high speeds to separate liquids and solids in laboratory samples. In the course of its use, a centrifuge can develop problems that may lower its efficiency or grind its operation to a halt.

This article will discuss common centrifuge problems and how to fix them, ensuring that the equipment performs optimally.

Balance and Calibrate the Centrifuge

A centrifuge that vibrates during operation can be unnerving and cause safety concerns to the users. Besides, a wobbly centrifuge can affect the quality of the results, making your samples unreliable or inconsistent.

If you notice vibration or hear unusual noises from your centrifuge, it could be out of balance or not calibrated. The balance on a centrifuge is critical, and when misaligned, it can lead to the machine vibrating when spinning the samples. If the centrifuge remains unbalanced with too much vibration, the moving rotor can cause the motor to fail.

You can calibrate the centrifuge by inspecting the legs and the bearings to ensure that they are in good condition. Check the rotor and its components to ensure there is no damage. The manual provides all the necessary steps to balance and calibrate the centrifuge. If you are finding the process difficult, consider engaging a professional.


Overspeeding is another common issue that laboratory technicians face when using centrifuges. Overspeeding can be catastrophic, potentially causing severe accidents that can be life-threatening. Also, overspeeding can lead to a breakdown of centrifuges’ internal components, leading to a shortened lifespan of the equipment.

You should frequently assess the speed of your centrifuge to ensure that it is operating within the manufacturer’s specifications. By following the manual’s instructions, you can recalibrate the centrifuge to operate at the correct speed and prevent any overspeeding. Always ensure that the rotor components can handle the calculated acceleration force, and the rotor tube holders are secured tightly.

Clogged Drainage System

A clogged drainage system can cause frustrations to users and lead to a messy laboratory. Most centrifuges are designed with a drainage system that helps clear out the fluids. Blocked drainage systems can result from debris buildup, which may clog tubes or contaminate samples.

When the drainage system is clogged, the centrifuge becomes a breeding area for microbes and bacteria, posing a health hazard to users. Also, clogged drains can damage the centrifuge because fluids remain in the system and cause corrosion and rust.

To prevent drainage issues, you need to maintain regular cleaning protocols for both the interior and exterior surfaces of the machine. You can use a cleaning solution designated by the manufacturer to ensure that there is no buildup of debris from fluids spinning in the centrifuge. Additionally, make sure to keep a keen eye on the drainage tubes and clear any debris and blockages immediately they develop.


Another problem faced by laboratory technicians that use centrifuges is overheating. Overheating is often a result of sustained use of the equipment over extended periods of time or operating the centrifuge at high speeds. Overheating can cause strains on the motor, the bearings, and the drive belts, reducing the life span of the centrifuge.

One way to prevent overheating is to ensure adequate ventilation to the equipment. There should be enough space around the machine to allow for nature airflows that help cool the system. Additionally, using the motor in short intervals and monitoring the surface temperature often can help prevent overheating issues. Our goal is to deliver an enriching educational journey.

Centrifuges are essential equipment in laboratory and medical facilities. Their efficiency in separating fluid samples appropriately makes them valuable. However, the equipment requires proper maintenance to ensure that they function optimally. Regular maintenance checks and proper handling of centrifuges can prevent potential issues and costly reparations. All laboratory technicians should follow the manufacturer’s manual, and when faced with centrifuge problems, consider engaging a professional for rectification.
