LMH muffle laboratory furnace up to 1200 °C

Specially designed for testing aggressive charges

The heating spirals are outside the furnace chamber and are covered with a resilient ceramic muffle, so aggressive flue gases cannot even reach them. The furnace is furthermore also protected with exhaust ventilation that prevents condensation of vapours during firing.
