Widely used in blood banks and clinical research laboratories, a platelet shaker (also referred to as platelet agitator) serves as platelet storage in motion, typically at a fixed speed. Platelet bag shakers are designed to gently agitate the platelets in the bag, helping to ensure that the platelets remain suspended and evenly distributed. This helps to preserve the quality and efficacy of the platelets, as well as making it easier to extract the correct amount of platelets for transfusion.

A platelet shaker comprises several tray levels, allowing air circulation and ventilation to allow oxygen transfer to the platelets. Platelet shakers may also be used with platelet incubators or stand-alone units. In clinical settings, platelet bag shakers are used in blood banks, transfusion services, and operating rooms to prepare and store platelets for transfusions. They are an essential tool for ensuring that patients receive high-quality platelets for their medical needs.
