Analytical Devices: Ashing Furnace

Summary :

ASHING FURNACES WITH FLAP DOOR OR LIFT DOOR

The ashing furnaces LV 3/11 - LVT 15/11 are especially designed for ashing in the laboratory. A special air intake and exhaust system allows air exchange of more than 6 times per minute. Incoming air is preheated to ensure a good temperature uniformity.

• Tmax 1100 °C

• Heating from two sides

• Ceramic heating plates with integral heating element which is safeguarded against fumes and splashing, and easy to replace

• Air exchange of more than 6 times per minute

• Good temperature uniformity due to preheating of incoming air

• Insulation made of non-classified fibre material

• Housing made of sheets of textured stainless steel

• Dual shell housing for low external temperatures and stability

• Optional flap door (LV) which can be used as work platform or lift door (LVT) with hot surface facing away from the operator

• Solid state relays provide for low noise operation

• Defined application within the constraints of the operating instructions

Additional equipment

• Over-temperature limiter with adjustable cut out temperature for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the furnace and load

• Process control and documentation via VCD software package for monitoring, documentation and control

EXHAUST SYSTEMS/ACCESSORIES

• Chimney for connection to an exhaust pipe.

• Catalytic converter with fan for removal of organic components from the exhaust air. Organic components are

• Catalytically oxidized at about 600 °C, broken into carbon dioxide and water vapour. Irritating odors are thus largely eliminated. The B400 - P480 controllers can be used to switch the catalytic converter automatically (not for models L(T) 15., L 1/12, LE 1/11, LE 2/11). Chimney with fan, to remove exhaust gas from the furnace better. The B400 - P480 controllers can be used to activate the fan automatically (not for models L(T) 15., L 1/12, LE 1/11, LE 2/11).

• Exhaust torch to burn exhaust gases which are generated during the process. The torch is gas-fired and will be operated with propane gas. If a catalytic post combustion cannot be used for the process this torch is recommended.

• Round saggar (Ø 115 mm) for furnaces LHT/LB, Tmax 1650 °C These saggars are perfectly suited for furnaces LHT/LB. The load is placed in the saggars. Up to three saggars can be stacked on top of each other in order to use the overall furnace chamber.
