Choosing a centrifuge may seem technical, but it is essential for ensuring the reliability of your analyses and the safety of your samples. With the various models, speeds, capacities, and specific uses, it is difficult to navigate without a guide. In this article, we explain step-by-step how to choose the right centrifuge according to your real needs.
Understanding how a centrifuge works
A centrifuge is a device used to separate the components of a liquid mixture according to their density, using centrifugal force. Used in biology, chemistry, medical, and food analysis laboratories, it is essential for isolating the solid and liquid phases of a sample.
What are the different types of centrifuges?
- General-purpose centrifuge: for standard tube separation applications.
- Refrigerated centrifuge: ideal for heat-sensitive samples like proteins or enzymes.
- Micro-centrifuge: adapted for very small volumes, often used in molecular biology.
- Ultracentrifuge: for very high speeds and complex separations (DNA, viruses, lipoproteins).
Technical criteria for choosing your centrifuge
- Capacity (rotor volume): based on the number of samples processed.
- Maximum speed (RPM or RCF): the higher it is, the faster the separation.
- Refrigeration: essential for heat-sensitive substances.
- Rotor type (fixed angle or swinging bucket): influences the type of sedimentation desired.
- Noise level: important for daily use in a laboratory.
Comparing these different criteria makes it possible to select a device truly adapted to the laboratory's needs. The laboratory centrifuges available are distinguished in particular by their capacity, maximum speed, footprint, and compatible rotors.
Why is the centrifuge a strategic piece of equipment?
A well-chosen centrifuge not only optimizes laboratory productivity but also ensures the stability of results. It allows for the rapid processing of a large number of samples with minimal manual intervention.
How to adapt your choice to your needs?
Here are a few questions to ask yourself before purchasing:
- Do you handle heat-sensitive biological samples?
- Do you work with large volumes or in series?
- Are you looking for a quiet model for a calm environment?
- Do you want a rotor compatible with several types of tubes?
What budget should you plan for a centrifuge?
The price of a centrifuge varies according to speed, rotor type, the presence of a refrigeration system, and the brand. Estimates include:
- Entry-level: from €80 to €500 for simple micro-centrifuges.
- Mid-range: from €500 to €2,000 for standard models with precise speed control.
- High-end: over €3,000 for professional refrigerated centrifuges and ultracentrifuges.
Where to find a reliable, refurbished centrifuge?
At Rewake, we offer a wide selection of refurbished, tested, and guaranteed laboratory centrifuges. You benefit from the same reliability as a new model, at a cost up to 50% lower.
Tips for maintaining your centrifuge
- Regularly clean the rotor with a soft cloth and ethanol.
- Avoid overloading tubes: respect balancing.
- Perform annual maintenance to check speed and braking.
- Store in a dry, dust-free environment.
