GSL-1500X-MGI-4 Four-Channel 1500°C Tube Furnace with 50mm Alumina Tubes for High-Throughput Annealing
The GSL-1500X-MGI-4 is engineered to facilitate high-throughput heat treatment experiments, enabling researchers to process four samples simultaneously under independently controlled temperature conditions. This capability is particularly valuable for investigating phase diagrams and thermal properties of advanced alloys and ceramic materials, supporting efficient comparative studies within a compact footprint.
Each of the four heating modules incorporates a high-purity alumina tube with an outer diameter of 50 mm and length of 460 mm, providing a stable and inert environment for sample processing. The furnace supports continuous operation at 1400°C and can reach a maximum temperature of 1500°C for short durations (under one hour). Temperature uniformity is maintained within ±10°C over a 120 mm zone at 1300°C, ensuring consistent thermal conditions for all samples.
Key Features
- Four independent heating zones with MoSi2 heating elements for precise temperature control.
- High purity alumina tubes (Ø50 mm x 460 mm) included for each channel.
- Programmable Eurotherm 3000 series controllers with 24-segment profiles and RS485 communication for PC control and data logging.
- Vacuum and gas flow capability with quick-seal KF25 flanges, mechanical vacuum gauges, and flowmeters for controlled atmosphere processing.
- Maximum continuous temperature of 1400°C; short-term peak up to 1500°C.
- Heating rate up to 10°C/min with temperature accuracy of ±0.5°C.
- Single vacuum pump connection supports all four tubes with max vacuum down to 10^-5 torr.

Typical Applications
This furnace is suited for high-throughput annealing and heat treatment of alloy and ceramic samples, enabling phase diagram research and material property evaluation under controlled atmospheres including vacuum and flowing gases.
Its multi-channel design allows simultaneous processing of samples at different temperatures, optimizing experimental efficiency in materials science laboratories.
Configuration & Operating Notes
The furnace includes four alumina tubes, flowmeters, quick-seal KF25 flanges, mechanical vacuum gauges, and needle valves. A single vacuum pump can serve all four tubes via the KF25 port. Power cable is provided without a plug; users must install a compatible plug locally.
Maximum operating pressure is 7.5 PSI (0.5 atm); installation of a pressure regulator on gas tanks is required to prevent overpressure. The system can be customized for larger chemical vapor deposition (CVD) applications with appropriate gas delivery modifications.
