H-1400ST tube furnace
H-1400ST horizontal tube furnace adopt a 40,60, 70, 80 or 100mm O.D quartz tube and a pair of stainless steel vacuum sealing flanges with needle valves & gauge allow heating samples under vacuum or gas flow conditions. The temperature of this tube furnace is controlled by a high precision digital controller which provides 51 programmable segments with +/- 1℃ accuracy. The max. working temperature is 1400℃.

Ⅱ.Application Notes |
|
Using Attentions |
● Cooling rate shall also not exceed 5 ℃ /min. ● Toxic or explosive gases are not recommended for use with this furnace without necessary safety controls and supervision. ● Small cracks may appear on the surface of the refractory ceramics over extended use. ● The tube furnace is avoid use vacuum above 1500 ℃, otherwise the tube will be serious deformation. |
