Customized TGA Vacuum and Atmosphere Controlled Tube Furnace optional 1200 - 1700C - OTF-X-TGA

0.0/5 rating (0 votes)


This is a customized vertical tube furnace from 1200 °C to 1700 °C with TGA (thermal gravimetric analysis) function.  Compared with conventional TGA devices, the TGA furnace can load larger samples up to 100 g to get a more accurate result for industry and can be operated under both vacuum and controlled gas atmosphere, even under hydrogen gas to research phase transition during material processing. The TGA furnace also may connect a gas analysis device to study gas composition change during heating and weight change.
