Abstract: A platelet incubator usable as a lid for a refrigerated container includes a heating plate and a transparent cover. The heating plate has an aluminum top plate, an aluminum middle plate with an opening into which a silicon mat heater is placed, and a 5052 aluminum alloy bottom plate, with an aperture through which the wires providing electrical energy to the silicon mat heater are placed. The temperature is continuously monitored, and a log is kept for printout, allowing the platelet incubator to meet relevant compliance requirements. An alarm is activated if the temperature of the platelets exceeds twenty-three degrees Celsius, or falls under twenty-one degrees Celsius.
