Alumina Ceramic Tube: 2 3/8" (60 mm) O.D.x 2 1/8" (54 mm) I.D x 31" (790 mm) L for GSL1700S60 Tube Furnace - EQ-TA-60D-M790

2 3/8" 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:

• Purity: Al2O3 > 99.8%
• Density: > 3.91 g /cm³
• I.D: 53.97 mm (2 1/8")
• O.D: 60.33 mm (2. 3/8")
• Length: 790 mm (31")
• Max. working temperature: 1750 ^oC
• Warning: 
  • Please don't use alumina tube under vacuum at temperature > 1500 ^oC
  • Please always keep heating or cooling rate less than 5^oC/ minute
  • Please keep theral gradient less than 100^oC/ minute to avois cracking
  • Please handle the tube carefully. No any warranty for the tube.
