Centrifuges must be what size?

Centrifuges must be what size?

• A. 10 ml
• B. 50 ml
• C. 100 ml
• D. 5 ml

Answer: (B)

In this context, using a standard tube size matters for safety, balance, and compatibility with the equipment. Fifty milliliters is the common, practical size because it fits the typical centrifuge rotors and adapters used in lead sample processing, provides enough liquid and sediment for reliable analysis, and allows the tube to be sealed and handled safely. Smaller tubes (like five or ten milliliters) often don’t hold enough material and can be unstable or incompatible with the rotor. A much larger tube (such as a hundred milliliters) may not fit the rotor or could overwhelm the centrifuge’s capacity and balance requirements, increasing the risk of spills or equipment damage. So, fifty milliliters is the best fit because it aligns with standard lab practices and safe, effective centrifugation for these samples.
