Specifications

 3.0" OD larger diameter Alumina tube is made of high purity 95% Al 2 O 3 material. Such an alumina tube can be used at operating temperatures to 1700 o C in both oxidizing and reducing atmospheres. Tubes have been evacuated to 10 -7 Torr at room temperature . SPECIFICATIONS Purity Al2O3 > 95%, SiO2 < 0.25%, CaO+MgO < 0.3% O.D 3.00" +/- 0.04 ( 76 +/- 1 mm) I.D 2.64" +/- 0.04 ( 67 +/- 1 mm) Tube Length 1000 mm Detailed dimension drawing Purity > 95% Max. Working Temperature 1700 °C (3092°F) Warning Do NOT use an alumina tube under a vacuum at a temperature > 1500°C. Max heating or cooling rate < 5°C/ minute. Please keep the thermal gradient less than 100°C/ inch to avoid cracking. Please separate parts from the inside surface of the tube to avoid thermal shock. Please handle the tube carefully. No warranty for the tube.
