1100℃雙管三溫區管式爐（石墨烯生長）- GSL-1100X-III-D11-8
GSL-1100X-III-D11-8  is adual tube & three zone tube furnace with 11" + 8.5" O.D two quartz tubes, vacuum flanges & valves snd vacuum gauge for immediate use. Three 30 segments programmable controllers are built in with K type thermal couple. Microprocessor-based PID control provides excellent control without overshooting and +/- 1 ºC accuracy. This new furence  is used for growwing graphene film on metallic foil which is wrapped on the wall of inside tube.

Dual quartz tube structure	·                                 High purity quart tube ·                                 Outside tube Size: 279 O.D x 269 I.D x 1300mm Length (11" O.D x 10.6" I.D x 48" L), two end opened and connected flange ·                                 Inside tube size :  216 OD x 206 IDx 750 mm Length (8.5"OD x 8.1"ID x30"L), one end closed and connected to gas inlet and outlet. ·                                  Please click picture below to see dual tubes anf flange set-up ·
Furnace structure	·                                 Double layer steel casing with air cooling.  Surface temperature of case is < 70°C. ·                                 Refractory fibrous alumina insulation liner for maximum energy saving. ·                                 Heating element: NiCrAl Resistance Wire ·                                 Two quartz block are included to  blco heat radiation ·                                 If take inside tube out is furnace also  can be used as annealing or diffusion furnace for 8" wafer use a quartz boat at related product below ·
