On a limited basis some are used as a dry incubator. In many cases, precise temperature control is required. Clinical ovens may be bench, cabinet, or walk-in size. However, bench top are the most common in the developing world. All ovens will include a heat source, a well insulated container (usually including a door with tight sealing gaskets), and a thermostat/thermometer. More advanced ovens may include timers/alarms, fans to circulate air inside the oven to achieve uniform heating, shelving units or racks, humidity control options, or air filtration. The heating mechanism may be electric, natural gas, propane, oil, radiofrequency or microwave, but the electric heater is the most common in the developing world.en-USOvenLaboratory OvenBook chapter
