SPECIFICATIONS:

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°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 user responsibility Adjusting two heating zone's temperature can create different thermal gradient profile Adjusting furnace opening diameter also can change the thermal gradient Click Pic left to see detail specs of the dual-zone furnace
Hanging wire	One set of Ni-SS hanging wire is included (pic to the left). Max. working temperature is 800C. Optional hanging wire for higher working temperature is available upon request: Ni-Cr-Al wire (not included) Max. working temperature < 1100°C Platinium wire (not included) Max.working temperature > 1200°C and < 1600°C 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 as Pic below right 800C pulling wire (Ni-SS)        sealed quartz tube as the crucible
Motor and Controller	6"L x 4"W Touch Screen Wire descending speed is programmable within 3 segments. Precise DC step 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 - 240V C Optional:   Lower speed range is available upon request at extra cost.
Compliance	CE Certified NRTL certification is available upon request at an extra cost
Laptop, software & WiFi Control (Optional)	Brand new laptop with Microsoft Window 10 and Microsoft Office 2013 (30 days free trial) Labview Based Temperature Control System (MTS01) enables the user to edit temperature profile, manage heat-treatment recipe, record and plot data for MTI furnaces A wireless remote control provides up to 300 meters operating range
Warranty	One-Year limited warranty with lifetime support Consumable parts such as processing tubes, O-rings, and heating elements are not covered by the warranty
Application Notes	In order to get better film coating, the substrate shall be treated by plasma cleaner (Please click on the first picture
