OTF-1200XS5-ASD is a 5" OD tube furnace with a fully automatic operation if paired with a robot. It automates the vacuum sealing, purging, heating, and cooling in a sequence via one click. Fully automation can also be realized via a laptop and a robot, including remote control, data logging, sample loading, and unloading. The maximum working temperature is 1200°C.
