LMV vertical muffle furnace up to 1200 °C

Top-loaded furnace for testing aggressive charges

Choose this muffle furnace variant when you need to lower and load the charge into the furnace from the top. In this muffle furnace as well, 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.
