A platelet collecting apparatuscomprises a centrifugal separatorpossessing a rotatable rotor; a first linefor allowing the flow of the blood entering the centrifugal separator; a second linefor allowing the flow of the blood emanating from the centrifugal separator, a plasma collecting bagconnected to the first lineand the second lineso as to collect the plasma emanating from the centrifugal separatorand return the collected plasma to the centrifugal separator, a platelet collecting bagconnected to the second lineso as to collect the platelets emanating from the centrifugal separator, a blood delivering pumpdisposed in the first line, and a controllerfor controlling the operation of the rotor of the centrifugal separatorand the operation of the blood delivering pump. The controlleris endowed with a function of varying the rotational frequency of the rotorduring the course of blood collection in conformity with the amount of the blood entered into the centrifugal separatorvia the first line
