Item Number: GSL-1600X-FS3KW
Transported by LTL Freight (Truck)
GSL-1600X-FS3KW  is a horizontal tube furnace with a 3KW programmable AC power source designed for exploring the flash- sintering for ceramic materials at a lower cost.  The tube furnace comes with an 80mm OD alumina tube and a sliding sample fixture, which can preheat sample up to 1600oC.    The Sample holder will press electric wire to the sample via a ceramic screw to pass through a programmable AC power source which is programmable up to 1500W power.
Flash-sintering is a new technology that is used widely in the research of solid-state electrolyte, SOFC, and magnetic & Thermo-electric materials.

Vacuum Sealing Flanges
& Sample Fixture

Vacuum Flanges are made of stainless steel which can reach the vacuum to 10-2 torr by mechanical pump and 10-5  torr by turbopump. (Please check the installation instruction at the Operation Video column)
Left Side Flange:
  • 30 mm dia. quartz observation window
  •  Needle valve with 1/4 NSP connector
Right Side Flange:
  • KF25 vacuum port to connect to a vacuum pump
  • Two electric wires feed through. Wires are made of Platinium with 1 mm diameter
  • Needle valve with mechanical vacuum gauge.
  • The sample fixture is built-in in the inside flange.
  • This flange is slidable to make sample loading easy.

Programmable AC Power Source

 The programmable AC power source is to connect the electric wire at the feedthrough at the right side flange.  After pre-heating,  AC power will pass a sample as a program set to produce more heat rapidly, which results in a sample sintered in high density.  The power parameters can be set via included laptop. Power source specifications ae as the below
  • Input Voltage:                  AC220V±10%,  50/60Hz, single phase
  • Power Capacity:              3000 W Max.
  • Circuit Type:                    IGBT, PWM
  • Output Voltage:             50V-300V adjustable with ≤1% stability
  • Output Frequency:           50/60Hz fixed with ≤0.01% stability
  • Protection:                       Overload, over-temperature, and short circus
  • PC programmable:        Laptop  with pre-installed software is included for program setting
  • Optional:                          DC power  source 400V/10A is available upon request at the extra cost
Optional Parts
  • Anti-Corrosive digital Gauge up to 10E-5 torr is optional for CVD application (Pic 3)
  • You may order a multi-channel gas delivery system for DVD or CVD operation ( Pic 4)
