Compact Bridgman Crystal Growth Furnace with Hanging Wire Mechanism

Vertical Two Zone Tube Furnace

• Compact two zones split vertical tube furnace

• Working Voltage: 110V AC or 220V selectable

• Max. Power Consumption: 1.5 KW

• Two Heating Zone: 100 mm L for each Zone, 200 mm L in total 

• Max. heating temperature: 1200℃

• Continuous working temperature: 1100℃

• Two programmable digital temperature controllers which control two heating zone independently

• Max. Temperature gradient: 1℃/Cm

• Finding a suitable thermal gradient is 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 (2" quartz tube (50mm O.D x 44mm I.D x 600mm L) is included with sealed flange)

Hanging wire

• One set of Ni-SS hanging wire is included. Max. working temperature is 800℃.

• Optional hanging wire for higher working temperature is available upon request:

• Ni-Cr-Al wire (not included) Max. working temperature < 1100℃

• Platinium wire (not included) Max.working temperature > 1200℃ and < 1600℃

• A thin hanging wire goes through the top flange. A positive inert gas can keep processing tube under controlled atmosphere

• For air-sensitive material, the sample shall be sealed in a small quartz tube with pre-vacuumed

Motor and Controller

• 6"L x 4"W Touch Screen

• Wire descending speed is programmable within 3 segments.

• Precise DC stepper motor controls traveling speed.

• Pulling speed range: 1-500 um/sec adjustable with the accuracy of +/- 0.05% 

• Total stoke length controlled by touch screen: 350mm

• Power: 50W, 110V - 240VC

• Optional: Lower speed range is available upon request at extra cost.
