Excerpt from Fact Sheet: "There are three general classes of centrifuges in use at the University of Massachusetts, Amherst. Low speed centrifuges, which do not exceed 5,000 rpm, are commonly found on the bench top. High speed centrifuges, which do not exceed 25,000 rpm, are generally floor models. Ultracentrifuges, which may exceed 100,000 rpm, are often found in core equipment areas and are the most expensive and most dangerous centrifuges on campus. Knowledgeable use, careful procedures, and preventative maintenance are important for all centrifuges, but especially for ultracentrifuges."
