How to Choose the Right Centrifuge for Your Laboratory Needs

Selecting the right centrifuge represents a critical decision for any laboratory. This equipment serves as a cornerstone for numerous scientific procedures, from basic sample preparation to advanced research applications. To help ensure optimal performance, safety, and compatibility with your laboratory’s specific needs, multiple factors must be carefully evaluated.

Match the centrifuge to your application

Evaluate your laboratory’s specific protocols and requirements. Different scientific disciplines demand distinct centrifugation capabilities. Clinical laboratories typically require instruments certified for diagnostic testing, while research facilities might prioritize versatility across multiple applications. Whether you’ll be processing blood samples, performing cell culture work, or conducting molecular biology procedures, this will narrow down the centrifuge models matching your needs.

Choose centrifuge and rotor to fit your sample volume and format

The volume and container formats of your typical samples directly influence the appropriate centrifuge and rotor category. Microcentrifuges excel at processing small volumes in PCR tubes or microtubes, and compact centrifuges can spin microplates, making them excellent for molecular biology applications. Medium-capacity benchtop models accommodate standard conical tubes (15-50 mL), commonly used in cell culture and general laboratory procedures. Large-capacity floor-standing models can spin large collection tubes, bottles, blood bags, or BioProcess Containers (BPC).

Of course, choosing the right centrifuge isn’t just about application and volume. To see how speed, temperature control, sustainability, and other factors impact your decision, download the complete Centrifuge Buying Guide.

Balance speed with separation needs

Different centrifugation protocols require specific speed and force parameters to achieve proper separation. Low-speed centrifuges operating up to approximately 7,500 rpm are suitable for whole cell separation, basic pelleting, and many clinical applications. High-speed models reaching 20,000+ rpm become necessary for subcellular fractionation, protein purification, and advanced molecular applications.

Further considerations

Additional factors to consider include temperature control, laboratory space constraints, rotor versatility, and safety features.

Why sustainability matters more than ever

Environmental considerations have become increasingly important in laboratory equipment selection. Recent regulatory changes, including the EU F-Gas Regulation (EU) 2024/573 and similar US EPA initiatives, are driving manufacturers toward more environmentally responsible refrigeration systems. Advanced centrifuges now incorporate natural refrigerant cooling systems using either CO₂ (with a Global Warming Potential of 1) or R290 (with a GWP of 3) instead of traditional hydrofluorocarbons with much higher environmental impact. The energy efficiency of lab equipment also helps reduce the total cost of ownership. This includes not only the annual energy costs but also quality considerations, service offerings, rotor inspection programs, and more.
