1200°C Hybrid Muffle (6" x 6" x 7") and Tube Furnace (2" or 4" OD) - KSL-1200X-J-H

KSL-1200X-J-H is a hybrid Muffle/Tube Furnace with 1200 Max working temperature. It has a heating chamber of 6"x6"x7" as a box furnace and a 2” or 4" OD quartz tube with a flange can be inserted from the top as a vacuum tube furnace. It is 2 in 1 cost-effective solution for material processing.

SPECIFICATIONS:

Structure	High purity alumina fiber insulation surrounding the chamber provides maximum energy efficiency.  Heavy-duty double-layer structure with a cooling fan to keep furnace exteriors safe to touch.  Doble layer steel case with forced-air cooling to ensure lower safer surface temperature. One 2" or 4" Dia. hole is opened from the top of the chamber with a thermal insulation block When used as a tube furnace, a quartz tube with a flange will be inserted into the heating chamber.
Heating Chamber	Dimensions: 150mm(D) x 155mm(W) x 180mm(H), ( 6"x6"x7") Capacity 4.2 Liter or 0.44 cubic ft Working Temperature: 100-1200 °C continuously in the air or inert gas. ( 1000 max if used in vacuum ) Heating rate: 30°C/ min. Temperature Stability: +/- 1.0 °C K types thermocouple with Ceramic Sheath
Processing Tubes  (2" tube & CF flange)  (4" tube & CF flange) (3.1" tube & KF flange)  Tube Installation	A 2" or 4" quartz tube with a flange can be inserted into the heating chamber to treat the sample under a high vacuum or controlled atmosphere. Please choose from the product options bar. 2” tube size: 50 OD x 44 ID x 263 L (mm) 4“ tube size: 100 OD x 94 ID x 210 L (mm) 3.1" tube size: 80 OD x 73 ID x 300L (mm ) is available with KF flange.

Temperature controller (optional)	MTS02-Y Temperature control software kit (for YD518P series controllers) + 15" laptop package is available at the options bar. Click for detailed information about the MTS02-Y software kit.  Eurotherm temperature controller with +/- 0.1oC accuracy is available at the extra cost
Power	Voltage: 208 -240V Single Phase 50/60 Hz 2.5KW ( not suitable for running at 110V ) Note Power cable is included but without a plug. The plug would have to be installed by the customer or click the link below the picture to choose a plug according to your country or your lab requirement
Compliance	CE Certified NRTL (UL61010) or CSA certification is available upon request at extra cost.
Application Notes	For a longer service life of the furnace, we recommend to not exceeding the heating rate of 10°C/min. The cooling rate should not exceed 10 °C /min either. Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with the alumina coating  The heating module is easy to replace.
