Description

FURNACE CERAMIC MUFFLE LT9/11/SKM/B510, TMAX.1100
 lift d lift door, protective gas connection, hole for thermocouple in furnace door

 The muffle furnace L 9/11/SKM is particularly recommended for heat treatment of aggressive substances. The furnace has a ceramic muffle with embedded heating from four sides. The muffle furnace thus combines a very good temperature uniformity with excellent protection of the heating elements from aggressive atmospheres. Another aspect is the smooth, nearly particle free muffle (furnace door made of fiber insulation), an important quality feature.

Standard Equipment

Tmax 1100 °C
Muffle heated from four sides
