GSL-1100X-S-VTQ Air-tight Swing Quenching Tube Furnace with 2″ OD Quartz Tube, Vacuum Sealed Flange, and 1100°C Max Temperature
The GSL-1100X-S-VTQ is engineered for advanced materials research requiring controlled atmosphere heat treatment followed by rapid quenching. It accommodates samples inside a 2-inch outer diameter fused quartz tube, allowing heating up to 1100°C under vacuum or inert gas environments. This setup is ideal for studying phase transformations and microstructural changes in materials.
After reaching the target temperature, the furnace can be tilted up to 60 degrees to slide the sample into an integrated quenching tank containing water or mineral oil, enabling rapid cooling. The vacuum-sealed flange and quenching tank design ensure an air-tight environment, minimizing contamination and oxidation during processing.
Key Features
- Maximum operating temperature of 1100°C with optional upgrade to 1200°C using thermal insulation tape.
- 2″ OD fused quartz tube (50mm OD x 44mm ID x 600mm length) with 300mm single-zone heating length.
- Vacuum capability down to 10-2 torr with mechanical pump or 10-4 torr with turbo pump.
- Tiltable furnace design (up to 60°) for sliding samples into a 500ml quenching tank.
- 30-segment programmable temperature controller with PID auto-tuning and over-temperature protection.
- Double-layer steel casing with air cooling and high purity Al2O3 fibrous insulation for energy efficiency.
- Standard flange with 1/4″ barbed fittings, needle valves, mechanical vacuum gauge, gas outlet, and KF25 vacuum port valve.

Typical Applications
Ideal for materials science research involving phase transformation studies, heat treatment under vacuum or inert atmospheres, and rapid quenching to preserve microstructures. Suitable for ceramics, metals, and advanced composites requiring controlled thermal processing.
Configuration & Operating Notes
Optional accessories include turbo pumps for deeper vacuum, gas purification and circulation systems to maintain ultra-low moisture and oxygen levels, and laptop-based LabVIEW temperature control software with remote operation capability.
Users must install a two-stage pressure regulator on gas cylinders to limit pressure below 3 PSI for safe operation. Gas flow rates should be kept below 200 SCCM to prevent thermal shock to the quartz tube. Vacuum operation is recommended only up to 1000°C to avoid tube damage.
