Key Considerations For Choosing Optimal Lab Centrifuge 

3 min read

Centrifugation is a fundamental process in laboratories, and choosing a suitable centrifuge is crucial for getting accurate results. If you are in search of a lab centrifuge, then here are some key factors to focus on – 

  • Maximum revolutions per minute (RPM) and relative centrifugal force (RCF)
  • Rotor types
  • Temperature control
  • Safety features
  • Optimal placement in the lab
  • Warranty 

Hospitals, reference labs, clinics, toxicology labs, and more approach the Complete Laboratory Systems to buy centrifuges and tubes, fume hoods, reagents, integrated solutions, rapid testing, and various other lab products.   

Key considerations for choosing the right lab centrifuge 

Maximum RPM and RCFThe maximum RPM and RCF determine the force applied to samples during centrifugation. You need to understand the specific requirements of the intended applications, as different experiments need varying levels of force. For example, delicate samples such as DNA or proteins may require lower RCF, while cell separations may demand higher forces.

RotorsDifferent rotors are designed for specific applications, and having a variety of rotor options increases the versatility of the centrifuge. 

  • Swing-out rotors are suitable for larger volumes and offer easy access to tubes.
  • Fixed-angle rotors provide higher speeds and are ideal for pelleting applications. 

Consideration of sample container types and sizes is essential when selecting rotors to ensure compatibility with the intended experiments.

Temperature Control

Temperature control is a vital aspect, especially when working with temperature-sensitive samples. 

  • Centrifuges equipped with refrigeration systems maintain a constant and low temperature during operation, which helps to prevent sample degradation. This feature is essential in applications such as cell culture or enzyme assays, where maintaining sample integrity is critical. 

The ability to control both the temperature and duration of centrifugation ensures optimal experimental conditions.

Safety Features

Ensuring the safety of laboratory personnel and preventing accidents is of paramount importance. Safety features in a centrifuge include:

  1. Lid Locks: Lid locks prevent the centrifuge from operating when the lid is open, minimizing the risk of sample spillage or injury.
  2. Imbalance Detection: Centrifuges equipped with imbalance detection systems automatically shut down if an imbalance is detected, preventing damage to the instrument and ensuring the safety of samples and equipment.
  3. Emergency Stop Button: An easily accessible emergency stop button allows quick cessation of centrifugation in unexpected situations, enhancing overall laboratory safety. 

Optimal Placement in the Lab

Placing the centrifuge within the laboratory space is crucial for efficient workflow and safety. 

  • Centrifuges should be located away from high-traffic areas to minimize disruptions and accidents. 
  • Proper ventilation is essential, especially for refrigerated centrifuges, to dissipate heat generated during operation. 
  • The noise level produced by the centrifuge is also important, as noise can impact the working environment and adjacent lab spaces.

Warranty Considerations

  • A centrifuge with a robust warranty indicates the manufacturer’s confidence in its product and ensures that any unforeseen issues are promptly addressed.
  • Understanding the warranty terms, including coverage and duration, is essential for making an informed decision and safeguarding the investment in laboratory equipment.


Choosing an optimal lab centrifuge involves careful consideration of factors that contribute to the overall efficiency, safety, and reliability of the centrifuge, which ultimately impacts the quality of experimental results. 

By thoughtfully evaluating these aspects, laboratories can make informed decisions that align with their specific research needs and ensure the successful operation of their centrifugation processes.
