Continuous operation up to 1700 °C – Laboratory & Industrial Thermal Applications

This high-purity rectangular alumina boat with fitted lid is designed for demanding high-temperature laboratory and industrial thermal processes.

Manufactured from ≥99–99.7% Al₂O₃ advanced ceramic, it provides outstanding thermal stability, superior chemical resistance, and excellent mechanical strength during prolonged exposure to elevated temperatures.

The precision-machined alumina lid ensures controlled heating environments, reduces airborne contamination, and promotes uniform temperature distribution during calcination, sintering, material synthesis, and thermal analysis.
