1200°C Max. Small Bridgman Crystal Growth Furnace with Air-tight 80 mm Quartz Tube - SKJ-BG-1200

SKJ-BG-1200 is a small 1200ºC Bridgman crystal growth furnace with a 72 mm ID quartz tube and precision travel mechanism, which is designed for growing small size crystal under control atmosphere up to 1200oC

SPECIFICATIONS:

Vertical Two Zone Tube Furnace	Compact two zones split vertical tube furnace Working Voltage:  208 - 240V selectable Max. Power Consumption: 4.0 KW Two Heating Zone: 100 mm L for each Zone, 200 mm L in total  Max. heating temperature: 1200°C Continuous working temperature: 1100°C Two programmable digital temperature controllers which control two heating zone independently Max. Temperature gradient: 1ºC/Cm Finding a suitable thermal gradient is the user responsibility Adjusting two heating zone's temperature can create different thermal gradient profile Adjusting furnace opening diameter also can change the thermal gradient Quartz tube (80mm O.D x 72mm I.D x 800mm L) is included with airtight flange)
Travel Mechanism	DC motor with precision screw drives the furnace up or down for crystal growth Travel distance:  200 mm Max. Travel speed range:  0.03 mm /hr. -  30 mm /hr. adjustable with +/- 1 micron accuracy ( standard) Customized speed range is available upon request
Airtight Flanges	One pair of air-tight flanges is included for atmosphere control under vacuum The top flange has a mechanical vacuum gauge and 1/4" gas inlet The bottom flange has a KF25 vacuum port and 1/4" gas outlet  The bottom flange is driven by a DC motor up or down to load and unload crucible  60 Diax 71 mm H graphite crucible is included  ( click the link to order more) The crucible holder is built in the flange Vacuum level:  10-2 torr by mechanical pump and 10-5 torr by a turbopump Please click the picture below to order a vacuum pump
Control Panel	Touch screen control PC is included for control travel speed, travel distance,  temperatures of the furnace and crucible temperature separately, as well as gas pressure inside the tube. Two Eurothermo controllers and two K type thermal couples are included with +/- 0.1 oC accuracy One thermal couple controls the temperature of the furnace  One thermal couple displays the temperature of the crucible at its bottom One digital pressure sensor with solenoid valves are installed for controlling tube pressure at the constant from 0.01MPa - 0.02MPa Click the picture left to see the PC interface
