GSL1100X-NT Multi-Position Tube Furnace with Programmable Temperature Controller, Up to 1100°C
The GSL1100X-NT tube furnace is engineered for controlled thermal processing of small diameter samples ranging from 1 to 2 inches. It is particularly suited for applications requiring precise temperature profiles such as firing, sintering, chemical vapor deposition (CVD), vapor-liquid-solid (VLS) growth, and quenching tests. Its design allows flexible orientation, enabling vertical, horizontal, or angled positioning to accommodate diverse experimental setups and material processing needs.
This furnace integrates a high-precision PID temperature controller capable of programming up to 30 segments, including heating rates, dwell times, and cooling rates, ensuring accurate and repeatable thermal cycles up to a maximum temperature of 1100°C (for durations under one hour). The heating zone extends 12 inches (300 mm) with a constant temperature zone of 3.1 inches ±1°C, providing uniform thermal conditions essential for sensitive processes.

Configuration & Operating Notes
The furnace does not include quartz tubes, vacuum flanges, or vacuum gauges, which are sold separately. Compatible quartz tubes are available in 25 mm and 50 mm outer diameters with 610 mm length. The furnace chamber is designed for 2″ O.D. tubes but includes adapters for 1″ tubes. Optional accessories include advanced temperature control software and digital vacuum gauges for enhanced process monitoring.
When operating under vacuum or low pressure (<0.2 bar), ensure proper installation of a two-stage pressure regulator to limit gas cylinder pressure below 3 PSI for safety. Gas flow rates should be limited to under 200 ml/min to minimize thermal shock to quartz tubes. The furnace is CE certified; additional certifications such as NRTL or CSA are available at extra cost.
