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

process because of the hydrocarbons that are released. Hydrocarbons are
flammable and there is a risk that a flammable mixture could form inside the
furnace. Nabertherm offers tailored safety packages with respect to the process
and the volume of binder that allow the furnace to be operated safely.

This weighing furnace with integrated precision scale and software, was designed especially for combustion loss determination in the laboratory. The
determination of combustion loss is necessary, for instance, when analyzing sludges and household garbage, and is also used in a variety of other
processes for the evaluation of results. The difference between the charged total mass and the combustion residue is the combustion loss. During the
process, the software included records both the temperature and the weight loss.Standard Equipment
