Apparatus for maintaining the freshness of blood platelet concentrate and related solutions which require continuous agitation to maintain usuable shelf life. A container for holding platelet concentrate packets contains a series of parallel cells which are disposed at an oblique angle with respect to a horizontal plane. A plurality of platelet packet containers are disposed within an equal number of cylinders which are adapted to securely hold the containers. Each cylinder has circumscribed about the outer surface thereof a friction transfer surface, each of which is aligned to contact the friction transfer bearing surface of an adjacent cylinder. A rotating power source engages a friction transfer surface of a cylinder causing same to rotate, the rotational force being transferred to all adjacent cylinders. Environmental control means maintain an appropriate temperature state during the agitation of all platelet packets being operated upon.
