Abstract: An infield sterilizable, saline solution warming graduate for a surgical operating room includes a stainless metal graduate. The graduate has an outside wall suitably with a handle, an inside wall forming an open container with a saline solution sensor and a solution temperature sensor. The graduate has a base with a first DC electrical connector, status lights and a housing for enclosing a heater and a control circuit. A DC power source with a second DC electrical connector is connectable with the first base DC electrical connector for energizing the control circuit, sensors, lights and heater.
