2.36" x 2 1/8" (60 OD x 54 ID x 790mm L) Alumina Ceramic Tube - EQ-TA-60D-M790-LD

2-2/5" OD 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 1750 ^oC in both oxidizing and reducing atmospheres. Tubes have been evacuated to 10^-7 Torr at room temperature. 998 alumina tube proves inert to carbon and refractory metals in many severe situations:

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