Centrifuges are integral to any workflow that requires particle separation. Centrifuges can differ in their size, capacity, rotor speed, and intended application. With many different types available, it is important for you to identify the solution that best fits your lab’s needs.

5 Questions to Ask When Purchasing a Centrifuge

  1. What type of centrifuge do you need? (ultracentrifuge, microcentrifuge, clinical)
  2. Are the centrifuge rotors interchangeable? Can they be replaced if damaged?
  3. How quickly does the centrifuge speed up and slow down?
  4. How much space will the instrument occupy in your lab?
  5. What service options are available for the instrument?

Maintenance Tip

Regular cleaning of your centrifuge can help prolong the life of your rotor. Review your centrifuge’s manual for the best practices when cleaning your instrument. While cleaning your instrument, you should also take time to inspect your rotor for wear and tear. You should replace your rotor at the first sign of damage or rust as these rotors are prone to failure and may put your laboratory workers at risk.

Safety Tip

Always make sure your samples are balanced before operating your centrifuge. Imbalanced samples can result in tube breakage, exposing you to aerosolized samples when you open the instrument’s lid. More serious injuries can result from rotors that break due to sample imbalance. As an extra precaution, look for instruments that have auto-imbalance detection and will stop the centrifuge if an imbalance is detected.
