1700°C Max. Small Bridgman Crystal Growth Furnace with Air-tight 60mm Quartz Tube - SKJ-BG-1600

SKJ-BG-1600 is a small 1700 Bridgman single crystal growth furnace, equipped with an outer diameter of Φ60mm alumina tube and a precise furnace movement mechanism (maximum traverse of 200mm). This equipment is designed for growing small-sized metal, oxide, and other single crystals in an atmosphere-controlled environment and can also be used for directional solidification of polycrystalline rods.

SPECIFICATIONS: 

Power & Voltage	208~240VAC 50/60HZ 3kW Maximum
Specs	Heating zone length: 200mm Maximum heating temperature: 1650 Continuous working temperature: 1600
Thermocouples	One Type-B for temperature control One Type-B for the crucible
Travel Mechanism	Driven by a servo motor and a harmonic drive The servo motor and a high-precision linear module ensure that the furnace body moves smoothly. Two movement modes: slow lifting and fast movement Maximum travel distance: 200mm. Travel speed range: 0.03mm/hr  ~ 30mm/hr (adjustable, with an accuracy of +/- 1um) The travel speed range can be customized at extra cost
Airtight Flanges	A stainless steel water-cooled sealing flange system for sealing the alumina tube The top flange is equipped with a digital vacuum gauge and a Φ6.35mm gas outlet The bottom flange has a KF25 vacuum interface and a Φ6.35mm air inlet The bottom flange is driven by a stepper motor for lifting and loading the crucible The equipment comes with a graphite crucible with an outer diameter of Φ30mm, an inner diameter of Φ25mm, and a height of 50mm, with a shoulder angle inside The crucible holder is installed on the bottom flange
Temperature Controller	A Eurotherm EPC3000 temperature controller included  PID automatic temperature control system Intelligent 24-segment programmable control DB9 PC communication port Temperature control accuracy: ±0.5
Control Panel	Control the travel speed,  travel distance, and furnace temperature Displays the crucible temperature  Control the internal pressure of the furnace tube The temperature curve function displays the real-time temperature control curve and the temperature curve of the crucible, and the data can be saved, recorded, and exported It can be used with the heating furnace's heating curve to set the pre-pulling time, such as setting the pulling to start after 5 hours A digital vacuum gauge and an electromagnetic valve are installed on the sealed flange to control the constant pressure inside the furnace tube, with a control range of 0.01 MPa to 0.02 MPa
Optional:	10E-2 torr via dual-stage mechanical vacuum pump (Pic. 2) 10E-5 torr via Turbopump (Pic. 1)  The vacuum pump is optional. Please click here to choose a vacuum pump.  For oxygen-sensitive material, suggest using a recirculating gas purification system ( H2O, O2 < 1 ppm) to replace the turbopump (Pic. 3)   Pic. 1     Pic. 2    Pic. 3
Compliance	CE Certified NRTL certification is available upon request at an extra cost
