Electrically heated muffle furnaces are ideal for daily laboratory use. Units feature rust-free, textured stainless steel exteriors. The furnances have Tmax 1100 or 1200 °C. Models feature an adjustable air inlet which is integrated in the door, an exhaust air outlet in the rear wall of the furnace and a silent solid state power control relay.

• Heating on two sides by means of ceramic heating plates (heating on three sides for models L 24/11 - LT 40/12)
• Ceramic heating plates with integral heating element which is protected from fumes and splashing, and easy to replace
• Module lining is highly durable cured vacuum fibre
• Double walled casing for low external temperatures and high stability
• Fold down door (L models) can be used as work platform or lift door (LT models) with hot surface facing away from the operator
• Non-classified insulation avoids the potential risk of cancer

The muffle furnaces L 1/12 - LT 40/12 have been proven for daily laboratory use. These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. The muffle furnaces come equipped with either a flap door or lift door at no extra charge.
