Alumina Conical Crucible Flat Bottom No Lid is a high-purity ceramic container designed for high-temperature laboratory and industrial applications. Manufactured from 99% alumina (Al₂O₃), it provides excellent thermal stability, chemical resistance, and structural reliability under extreme heating conditions.
The conical shape with a flat bottom allows stable placement during thermal processing while ensuring efficient heat transfer and uniform temperature distribution. The open-top design (without a lid) makes it convenient for sample loading, observation, and processing in various experimental procedures.
