Description
Part Number: OTF-1200X-S-VT
OTF-1200X-S-VT is a compact-split Vertical Tube Furnace with vacuum sealed 1“, 2" or 2.36"(60mm) diameter quartz tube. It provides fast heating and quenching as well as the capability to heat samples under vacuum or flowing gas atmospheres. A precision temperature controller can provide up to 30 segments of heating, cooling, and dwelling steps with +/- 1 oC accuracy. It is an ideal furnace for carrying out quenching tests. New!!! the electric components of the 220V version OTF-1200X-S-VTare UL/CSA certified, and the 220V version is ready to pass UL or CSA certification (UL61010 or SPE1000) on customer side at customer cost.

Warning
Click here to learn the installation of a gas regulator | - Tube furnaces with quartz tube are designed for using under vacuum and low pressure < 0.2 bar / 3 psi / 0.02 MPa
- Attention: A two stage pressure regulator must be installed on gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
- Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
- The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
