Platelet Agitator Incubators keep platelet concentrates at 22 degrees C with gentle, nonstop agitation. Platelets need this motion for gas exchange through the bag wall and to avoid clumping. Platelets keep for only a few days, so stable storage matters. Forced air flows through perforated trays to hold the chamber between 22 and 24 degrees C. An alarm sounds if the temperature falls below 20 or rises above 24 degrees C. Trays move at 60 cycles per minute with a 20 mm stroke. Benchtop units store 5 to 10 bags, while 40-tray floor models hold 80 to 120 bags. These platelet storage incubators serve hospital blood banks, transfusion centers, apheresis units and blood donation services.
