Laboratory furnaces are used for heating applications that require a range of high temperatures. They heat to high temperatures evenly and maintain consistent temperatures, while providing an environment free of undesirable contaminants and moisture. Factors such as object size, controllers, temperature range, and shape determine the uses of particular furnaces. Most furnaces have digital controllers that determine how fast they heat up (ramp), how long the temperature can be held (dwell), and how fast they cool down. Safety systems are included in most furnaces to prevent overheating the contents, as well as the furnace itself. Laboratory furnaces are used in applications such as petroleum analysis, chemical analysis of certain compounds, and heat-treating small steel parts.Thermo Fisher Scientific manufactures analytical instruments, laboratory equipment, consumables, and software under the Thermo Scientific, Fisher Scientific, and Nalgene brands, among others. The company is headquartered in Waltham, MA.
