What factors should I consider when choosing a used centrifuge?
Consider the type of centrifuge (e.g., benchtop, floor-standing, refrigerated), maximum speed (RPM), rotor compatibility, and sample capacity to ensure it meets your laboratory’s needs.
Are refurbished centrifuges as reliable as new ones?
Yes, refurbished centrifuges undergo thorough inspection, testing, and calibration to ensure proper functionality, making them a cost-effective and reliable option.
How do I determine if a centrifuge is suitable for my application?
Check the speed (RPM), relative centrifugal force (RCF), and rotor type to match the centrifuge with your specific application, such as cell separation, DNA extraction, or protein purification.
Can I use different rotors with a used centrifuge?
Most centrifuges support multiple rotor types, but compatibility depends on the model. Always verify that the rotor you need is supported before purchasing.
What safety features should I look for in a used centrifuge?
Look for safety features like imbalance detection, lid-locking mechanisms, and automatic shutoff to ensure safe operation in the lab.
How do I maintain a used centrifuge?
Regularly clean the rotor chamber, check for wear on the rotor and seals, and ensure proper balancing of samples to maintain performance and longevity.
What is the typical lifespan of a centrifuge?
With proper maintenance, a centrifuge can last 10–15 years or more, depending on usage frequency and operating conditions.
Do used centrifuges require calibration before use?
Yes, calibration is essential to ensure accurate performance. Many refurbished units come pre-calibrated, but it's best to verify before first use.
