Trapezoidal 99% Alumina Combustion Boat for Lab Furnace 60*30*15mm 20pcs

This Trapezoidal 99% Alumina Combustion Boat is made of high-purity 99% alumina (Al₂O₃) ceramic, engineered for reliable performance in laboratory furnaces and high-temperature applications.

The trapezoidal (tapered) rectangular design features sloped sides and an open top, making sample loading, observation, and retrieval straightforward. Its 99% alumina composition delivers excellent thermal stability, withstanding continuous temperatures up to 1600°C, and outstanding resistance to thermal shock, acids, bases, and most molten materials, helping prevent sample contamination.

Ideal for use in tube and muffle furnaces, as well as ash analysis equipment, this combustion boat is perfect for ashing, sintering, calcination, thermal gravimetric analysis (TGA), and material testing. The dense, smooth surface is easy to clean and reusable, offering consistent performance for daily lab use and industrial processes.
