The muffle furnaces L 3/11 - LT 60/12 have been proven for daily laboratory use. These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability.
Standard Equipment
• Heating from two sides by ceramic heating plates (heating from three sides for muffle furnaces L 24/11 - LT 60/12) for an optimal temperature uniformity
• Temperature uniformity of +/− 5 K with closed fresh-air inlet in empty work space according to DIN 17052-1 at working temperatures above 800 °C
• Thermocouple type N (1100 °C)
• Ceramic heating plates with integral heating element which is safeguarded and easy to replace
• With flap door (L)
• Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
• Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• Adjustable air inlet integrated in door (see illustration)
• Exhaust air outlet in rear wall of furnace
• Controller with touch operation C550
• Solid state relays provide for lownoise operation
Option
• Chimney, chimney with fan or catalytic converter (not for L 1 and L 15)
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Protective gas connection to purge with non-flammable process gases (not available in combination with chimney, chimney with fan or catalytic converter) not gas tight
• Manual or automatic gas supply system
• Port for thermocouple in the rear wall or in the furnace door
