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. 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 Flap door which can also be used...

Heating elements on support tubes radiating freely into the furnace chamber provide for particularly short heating times for these muffle furnaces. Thanks to their robust lightweight refractory brick insulation, they can reach a maximum working temperature of 1300 °C. These muffle furnaces thus represent an interesting alternative to the familiar L(T) ../12 models, when you need a higher application temperature. ■ Heating from two sides ■ Heating elements on support tubes ensure free heat radiation and a long service life ■ Multi-layer insulation with robust lightweight refractory bricks in the...

These models stand out for their excellent workmanship, advanced and attractive design, and high level of reliability. Heating elements on support tubes radiating freely into the furnace chamber provide for particularly short heating times and a maximum temperature of 1400 °C. These muffle furnaces are a good alternative to the familiar L(T) ../12 series when higher application temperatures are needed. Standard Equipment ■ Tmax 1400 °C ■ Heating from two sides ■ Heating elements on support tubes ensure free heat radiation and a long service life ■ Adjustable air inlet integrated in door ■ Exhaust...

We particularly recommend the muffle furnace L 9/11/SKM 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 ■ Muffle heated from four sides ■ Furnace chamber with embedded ceramic muffle, high resistance to aggressive gasses and vapours ■...

Ashing furnace LV(T) .. 11 is designed especially for ashing processes to 1050 °C in the laboratory. Applications include determining loss on ignition, ashing food and plastics for subsequent substance analysis. A special fresh-air and exhaust air system ensures that the air is replaced 6 times per minute so that there is always sufficient oxygen for the ashing process. Incoming air passes the furnace heating and is pre-heated to ensure good temperature uniformity. Standard Equipment ■ Tmax 1100 °C ■ Heating from two sides ■ Ceramic heating plates with integral heating element which is safeguarded,...
