A centrifugal separator includes an input section for allowing a user to enter operating conditions of a centrifugal separation of a sample accommodated in a rotor driven by a motor. A memory of the centrifugal separator stores a user ID code and a corresponding user name which are registered in advance by the user. Operation of the centrifugal separator is allowed when a user ID code entered through the input section agrees with the registered user ID code.
