Electrically-heated muffle furnaces are ideal for daily laboratory use. Units feature rust-free, textured stainless steel exteriors. The furnaces 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
