Occasionally, large amounts of whole blood are difficult to obtain for physiological studies. Little blood is available when the animal is small (e.g. some fish and crustaceans) or when blood samples are taken periodically without sacrificing the animal. It is often difficult to obtain clear serum or plasma from small blood samples. In many microanalytical procedures (e.g. electrophoresis) only a few microliters of serum are needed, but the serum must be free of other blood components. Because of this, a simple and inexpensive device for separating components of small amounts of blood in a clinical-type centrifuge is described.
