They are durable, reliable, and work well for extensive use. Muffle furnaces are ideal for research and development, materials testing and quality control, heat treatment, ceramics, glass, and so much more.<\/p>\n<p class=\"desc-list\">There are so many muffle furnaces in the market. How do you choose? You want to keep in mind what your application needs and compare it against the following variables:<\/p>\n<ul>\n<li class=\"desc-list\">Operating temperature range<\/li>\n<li class=\"desc-list\">Size of the chamber<\/li>\n<li class=\"desc-list\">Overall dimensions of the furnace<\/li>\n<li class=\"desc-list\">Temperature uniformity<\/li>\n<li class=\"desc-list\">Rise time and at what temperature<\/li>\n<\/ul>\n<p class=\"desc-list\">The <strong>Cole-Parmer StableTemp muffle furnaces<\/strong> reach maximum temperature quickly\u2014rise times as fast as 25 minutes to 1020 degrees. These handy laboratory furnaces are available in three\u00a0sizes and three controller options to meet your\u00a0application requirements; basic, set-point, and programmable. All models have an autotuned feature which allows the furnace to perform better at a particular set point and load, eliminating temperature overshoot for a commonly used application. An optional RS-485 communications port is available to let you use these furnaces with your computer.<\/p>\n<p class=\"desc-list\">The fully embedded heating elements maintain temperature uniformity. A door switch cuts power to the heating elements when the door is opened minimizing your exposure to hot temperatures and extending the life of the heating elements. Unique ceramic fiber insulation and double walled construction minimize exterior surface temperatures. The removable hearth plate prevents damage to the furnace from spills. These furnaces have LED displays to simultaneously display actual and set point temperatures.<\/p>\n<ul>\n<li class=\"desc-list\"><a title=\"StableTemp Muffle Furnaces with Basic Control\" href=\"\/p\/stabletemp-muffle-furnaces-with-basic-control\/62828\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">Basic Control Furnaces<\/a> feature a single LED display that toggles between actual and set point temperatures.<\/li>\n<li class=\"desc-list\"><a title=\"StableTemp Muffle Furnaces with Single Set Point Control\" href=\"\/p\/stabletemp-muffle-furnaces-with-single-set-point-control\/62829\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">Single Set Point Control Furnaces<\/a> have two LED displays to simultaneously display actual and set point temperatures.<\/li>\n<li class=\"desc-list\"><a title=\"StableTemp Muffle Furnaces with Programmable Control\" href=\"\/p\/stabletemp-muffle-furnaces-with-programmable-control\/62830\" rel=\"nofollow noopener noreferrer\" target=\"_blank\">Programmable Control Furnaces<\/a> have two LED displays to simultaneously display actual\u00a0and set point temperatures.<\/li>\n<\/ul>\n<p class=\"desc-list\">Do you still need help selecting a muffle furnace to meet your application?
