A blood centrifuge is not chosen only by speed. For serum and plasma separation, the machine must match the lab’s blood tubes, rotor type, RCF requirement, spin time, sample volume, and safety needs.
When comparing centrifuge specifications, many buyers look first at RPM. A machine marked 5,000 rpm may seem weaker than one marked 10,000 rpm, and a 20,000 rpm centrifuge may look like the obvious upgrade.
Choosing a laboratory centrifuge is not just about finding the highest RPM or the lowest price.
A small blood sample can provide useful clinical information when it is prepared correctly. A hematocrit centrifuge is used to spin capillary blood tubes at high speed, separating red blood cells from plasma so users can read packed cell volume clearly.
