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.
A centrifuge that shakes, vibrates, or makes unusual noise is often warning the user that the load is not balanced. Balancing a centrifuge is one of the simplest but most important safety habits in daily laboratory work.
