What is the rpm range for a cytocentrifuge used for cell counts?

Explanation:
Cytocentrifugation for cell counts relies on gentle, low-speed spinning to push cells onto a small area of the slide and concentrate them without damaging cell morphology. Because the goal is to preserve cells while achieving a clean, evenly distributed deposit, the operating speeds are kept relatively low—typically from a few hundred up to about two thousand revolutions per minute. This is why 200–2000 rpm is the best fit; it covers the practical range that preserves cell integrity while producing a suitable smear for counting. Speeds much higher can crush or lyse cells and create artifacts, while the lower or mid-range limits within this window ensure a good balance between cell concentration and morphology.
