3.5" top, non-stirring hot plate. For laboratories where an inexpensive heat source is needed and bench space is scarce. Ruggedly built to withstand continuous usage. Cast aluminum heating surface reaches a top temperature of 371C (700F) in less than 7.5 minutes. The nickel-chromium heating element is embedded in special heat-conducting refractory material for maximum protection. Stepless, thermostatic control allows selection of temperature from approximately 38 to 371C (100 to 700F). Perforated stainless steel case.
