Alumina Tube: 3.25" ( 82mm ) O.D. x 40" L (1000 mm ) for GSL1600-80X Tube Furnace - EQ-TA-82D-M1000

.25" 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:

• O.D: 3-1/4 " +/- 0.13                   (82.55 mm)
• I.D:   2-7/8"    +/- 0.115                (73.03 mm)
• Tube Length:                               1000 mm 
• Max. Working Temperature:         1750^oC  ( unloaded  without vacuum )
• Fit and replace alumina tube for MTI tube furnace GSL-1600-80X
• Warning: 
  • Please don't use alumina tube under vacuum at temperature > 1500 ^oC.
  • Please always keep the 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.
