With their convincing price/performance ratio and the fast heat-up rates, these compact muffle furnaces are perfect for many applications in the laboratory. Quality features like the dual shell furnace housing of rust-free stainless steel, their compact, lightweight constructions, or the heating elements encased in quartz glass tubes make these models reliable partners for your application.

Standard Equipment

• Tmax 1100 °C
• Heating from two sides from heating elements protected in quartz glass tubes
• Fast heating times (see table)
• Maintenance-friendly replacement of heating elements and insulation
• Housing coated in RAL 9003
• Solid state relays provide for lownoise operation
• Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
• Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
• Flap door which can also be used as a work platform
• Exhaust air outlet in rear wall
• Compact dimensions and light weight
• Controller mounted under the door to save space
• Controller R7
• Defined application within the constraints of the operating instructions

Additional Equipment

• Chimney, chimney with fan or catalytic converter (not for LE 1 and LE 2)
