Cooling air enters through the furnace base and
passes upward between the outside of the
sample tube and the inside of the furnace,
completely separating the cooling air from the
sample and the sample zone.
The furnace is a resistance heater wound on
alumina ceramic, which allows sample zone
temperatures as high as 1000°C with heating
rates up to 50°C/min.
A Platinel II* thermocouple is positioned in the
furnace, just above the sample pan, where it
monitors the sample environment temperature.
The furnace base moves the furnace assembly
up around the sample pan to the closed position,
or down away from the sample pan to the open
position.
