L, LT 9/11/SKM

We particularly recommend the L 9/11/SKM model if your application involves aggressive substances. The furnace has a ceramic muffle with embedded heating from four sides. The 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 fibre insulation), an important quality feature for some ashing processes.

  • Muffle heated from four sides
  • Furnace chamber with embedded ceramic muffle, high resistance to aggressive gasses and vapours
  • Dual shell housing made of sheets of textured stainless steel
  • Only fiber materials are used which are not classified as carcinogenic according to TRGS 905, class 1 or 2
