2 3/8" x 31 1/2" (60 OD x 51 ID x 800mm L) Alumina Ceramic Tube - TA60D800

2 3/8" OD larger diameter Alumina tube with high purity 99% Al₂O₃ material. Such an alumina tube can be used at operating temperatures to 1700 ^oC in both oxidizing and reducing atmospheres. Tubes have been evacuated to 10^-7 Torr at room temperature. It proves inert to carbon and refractory metals in many severe situations:
