How to choose the right laboratory centrifuge a practical guide
In any laboratory, having the right equipment is essential to ensure accurate results, efficient processes and safe working conditions. Among the most important instruments are centrifuges, essential tools in many analytical, clinical and research procedures.

However, choosing a centrifuge is not always an easy task. There are different configurations, capacities, rotors and features, and the most suitable option will always depend on the type of sample, the application and the actual needs of the laboratory.
For this reason, we have prepared the video “How to choose the right centrifuge”, a practical guide in which we explain the main criteria to consider before selecting a unit.
The importance of choosing the right centrifuge
A centrifuge should adapt to the laboratory, not the other way around. A properly sized unit helps optimise working times, improve reproducibility of results and provide greater flexibility for new needs.
Before making a decision, it is important to assess technical and operational aspects that will directly affect equipment performance.
7 key points for selecting a laboratory centrifuge
1. Analyse the application and sample type
The starting point is to understand the intended use of the centrifuge. The needs of a clinical laboratory can be very different from those of research, microbiology, molecular biology or quality control laboratories.
Sample type and protocols will determine key factors such as required speed, working volume or the most suitable rotor.
2. Check capacity and compatibility
The centrifuge must fit the tube formats used regularly. Microtubes, larger-volume tubes or specific containers require specific configurations.
Selecting the correct rotor capacity and available adapters helps improve efficiency and avoid limitations in routine processes.
3. Consider centrifugal force and the right rotor
One of the most common mistakes is focusing only on revolutions per minute. In reality, relative centrifugal force (RCF) is a key parameter for determining separation efficiency.
The rotor also plays a decisive role:
Fixed-angle rotors are designed for applications requiring high speeds and rapid sedimentation.
Swing-out rotors enable more uniform separations in certain procedures.
The right combination of rotor and RCF ensures more consistent results.
4. Ensure operational safety
User and sample safety must be part of the selection process. Features such as automatic lid locking, imbalance detection or overspeed protection provide confidence and stability in daily work.
A safe device is also a more reliable device.
5. Consider versatility and maintenance
Laboratories evolve over time. Therefore, choosing a centrifuge that allows different rotors, accessories and configurations can make a significant difference in the medium and long term.
In addition, easy maintenance and an intuitive interface help reduce downtime and simplify daily use.
6. Evaluate available accessories
Accessories expand the centrifuge’s capabilities and allow adaptation to different protocols.
Additional rotors, specific adapters and compatible consumables provide greater flexibility and turn the centrifuge into a multi-purpose solution.
7. Think about the future of the laboratory
A centrifuge is an investment expected to support the laboratory for years. Therefore, the choice should not be based only on current needs, but also on future expansions and new applications.
The best solution is one that combines performance, safety, ease of use and adaptability.
A technical decision that impacts results
Selecting the right centrifuge is a strategic decision that directly affects laboratory work quality.
Proper evaluation of application, capacity, RCF, rotor type, safety and versatility allows you to choose equipment that adds real value and supports the laboratory’s goals.
