Three Zones Split Tube Furnace Optional from 60mm (2.36") t 127mm (5") O.D Quartz Tube and Vacuum sealing Flanges

It is an excellent furnace for annealing, diffusing and sintering sample in various atmospheres. Product Description

OTF-1200X-III series furnaces are CE certified long split-able three-zone tube furnace from 60mm (2.36") to 127mm (5") O.D tube size which can achieve faster heating up to 1200°C and create a different thermal gradient by adjust three zone temperature. The furnace includes one fused quartz tube, one pair of vacuum sealing flanges with pressure gauge & ball valve for immediate use. Three 30 segments temperature controllers are installed with K type thermal couple. Microprocessor-based self-tuning PID control provides excellent control without overshooting and  +/- 1 °C accuracy. It is an excellent furnace for annealing, diffusing and sintering sample in various atmospheres.
