 Split Long Tube Furnace with 4.5"OD x 4.3"ID x 59" L Quartz Tube (36" Heating Zone) & Vacuum Flanges

JZ-T1200-115 is a split single-zone tube furnace which has 4.5"OD x 4.3"ID x 59" L quartz tube and can achieve faster heating up to 1200ºC. The furnace includes one pair of vacuum sealing flanges and two vacuum valves & Pressure gauge for immediate use. The precision temperature controllers can provide 30-segment heating and cooling steps with +/- 1 ºC accuracy with 17" length constant temperature (flat) zone. It is an excellent furnace for annealing, diffusing and sintering samples in various atmospheres.
