Question

Centrifuges must be calibrated every what?

Answer 1

Centrifuges should be calibrated periodically based on the specific centrifuge type, usage, manufacturer's guidelines, and regulatory standards to ensure accuracy and safety.

Step-by-step explanation:

Centrifuges should be calibrated periodically to ensure that they are providing accurate readings and performance. The exact frequency of calibration may depend on the type of centrifuge, its usage, manufacturer's recommendations, and regulatory requirements. For example, a centrifuge used in DNA extraction that operates at 7000 rpm and generates forces of 6000 times the force of gravity would require precise calibration to maintain consistently accurate results. Additionally, human centrifuges that are used in astronaut training, which can achieve centripetal accelerations of several hundred thousand g in a vacuum, also demand regular and meticulous calibration. The calibration ensures the safety and effectiveness of high-stakes operations such as astronaut training or sensitive laboratory procedures.

Answer 2

You should aim to have your centrifuge serviced at least once per year or more often for heavily used machines. To ensure accurate results, it's also important to have the unit calibrated every 12 months, or every six months if it's used for six or more hours per day.
