Alumina Tube (≥99% Al₂O₃) – 1200 mm Length

S4R alumina tubes are made from high-purity alumina ceramic (Al₂O₃ ≥99%) and are designed for laboratory and high-temperature applications.

They offer excellent thermal stability, good chemical resistance, high hardness, and reliable electrical insulation. These tubes are suitable for tube furnaces, thermal processing, controlled-atmosphere experiments, and general laboratory setups requiring a stable ceramic tube. Under suitable operating conditions, alumina tubes can be used at temperatures up to approximately 1700°.

Standard length is 1200 mm, with custom lengths available on request depending on project requirements.
