Alumina Crucible with Lid (≥99% Al₂O₃) – Arc-Shaped Type

S4R arc-shaped alumina crucibles with lid are made from high-purity alumina ceramic (Al₂O₃ ≥99%) and are designed for laboratory, high-temperature, and thermal processing applications.

Their arc-shaped design is suitable for sample preparation, calcination, sintering, ash testing, thermal treatment, and material research. The fitted alumina lid helps protect samples, reduce contamination, and limit material loss during heating processes.

These crucibles offer excellent thermal stability, good chemical resistance, high hardness, and reliable performance in demanding laboratory environments.

Under suitable operating conditions, alumina crucibles can be used at temperatures up to approximately 1700°C.

Custom dimensions may be available on request depending on project requirements.
