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.
A laboratory may search for a sorvall centrifuge because the name is familiar, an older unit needs replacement, or the team wants a benchmark for speed, capacity, rotors, and safety.
Platelet-rich plasma preparation depends on careful blood separation, not just a simple spinning step.
