A system for collecting bio-waste material is provided. The receiver circuit includes a voltage limiter, a level down shifter and an inverter of low operation voltage. In particular embodiments, the removable controller device includes a user interface to readily provide information, for example, about the operation of the pump. This process makes it possible to obtain highly dehydrated ionic liquids. The method yields a notably high number of CD34+, ALDHbr andor ABCG2-expressing cells, comprising hematopoietic stem cells, permitting the use of the cells with no or minimal expansion. The copy controlling unit makes data stored in the recording unit to be stored in the storage unit of the information processing apparatus when the timer detects elapse of a first predetermined time duration, and the deleting unit deletes data stored in the recording unit when data stored in the recording unit is copied in the storage unit.
