GSL-1700X-MGI-4 Four-Channel Tube Furnace with 25mm Alumina Tubes for High-Throughput Annealing up to 1700°C
The GSL-1700X-MGI-4 is engineered to meet the demands of high-throughput heat treatment research, particularly for alloy and ceramic materials requiring precise thermal processing. This system integrates four independent tube furnace modules, each equipped with a 25 mm outer diameter alumina tube, allowing simultaneous annealing of multiple samples under controlled atmospheres.
Its compact design occupies minimal laboratory space with a footprint of just 1000 by 650 mm, making it suitable for labs with limited bench area. Each module features independent temperature control up to 1700°C, enabling flexible and precise thermal profiles tailored to diverse experimental needs.
Key Features
- Four independent tube furnace modules with 25 OD x 22 ID x 460 mm alumina tubes.
