Is 800 rpm within the specified cytocentrifuge speed range?

• A. Yes
• B. No
• C. Sometimes
• D. Not specified

Answer: (A)

The concept tested is whether a given rpm falls inside the manufacturer-recommended speed window for cytocentrifugation. Cytocentrifugation relies on a specific speed range to deposit cells onto slides without causing excessive shear or damage. 800 rpm is a moderate speed that many cytocentrifuge protocols use, typically within a common window such as roughly 600–1000 rpm (or 500–1200 rpm, depending on the rotor). Since 800 rpm lies comfortably inside these typical ranges, it is within the specified speed range, assuming the device’s own manual confirms that range. The key idea is that the speed must be within what the equipment and protocol specify; the exact g-force depends on rotor radius, but rpm itself being within the recommended window ensures proper deposition and cell integrity.
