LTF - Tube furnaces : 1400°C, 1500°C & 1600°C
Heating is provided by silicon carbide rod elements which are mounted parallel to the work tube (the work tube must be ordered
separately).

The elements radiate heat directly onto the tube for rapid response rates. Low thermal mass insulation is used throughout for maximum thermal efficiency and stability.

Horizontal models are supplied with the controls in the base, whilst vertical versions have a separate console (shown right).
