Ashing Furnaces up to 1100 °C

Ashing furnace LV ../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, and
easy to replace
· Air exchange of more than 6 times per minute
· Good temperature uniformity due to preheating of incoming air, temperature
uniformity according to DIN 17052-1 to +/− 10 °C in the defined empty work area
(from 550 °C)
· Suitable for many standardized ashing processes according to ISO, ASTM, EN,
and DIN
· Optional flap door (LV) which can be used as work platform or lift door (LVT) with
hot surface facing away from the operator
· Controller B410 (5 programs with each 4 segments), alternative controllers

Additional Equipment
· Over-temperature limiter with adjustable cutout temperature as temperature
limiter to protect the oven and load
· Port for thermocouple in the rear wall or in the furnace door
· Charging rack with closed or perforated trays for loading the furnace in two
levels incl. holder for inserting/removing the trays up to a max. temperature of 800°C and a max. loading weight of 2 kg for the LV(T) 9/11 respectively 3 kg for
the LV(T) 15/11
