2" x 47" (50 OD x 44 ID x 1200mm L) Alumina Ceramic Tube (99.8%) High Purity - EQ-TA-50D-M1200-LD

2" larger diameter Alumina tube is made in USA with high purity 99.8% ( 998) Al₂O₃ material. 998 alumina tube can be used at operating temperatures to 1800 ^oC in both oxidizing and reducing atmospheres. Tubes have been evacuated to 10^-7 Torr. 998 alumina tube proves inert to carbon and refractory metals in many severe situations. SPECIFICATIONS

Warning	Please don't use alumina tube under vacuum at temperature > 1500 oC when vertically-mounted and >1400 oC when horizontally-mounted Mcdanel strongly recommends keep ramp rate less than 100oC/ hour Please keep thermal gradient less than 100oC/ inch to avoids cracking Parts should not be placed directly onto the inside surface of a hot furnace tube in case of thermal shock Please handle the tube carefully. Warranty does not include tube (but only for machine MTI provided)
