2" O.D Mullite Tube is made in the USA with 60% Al₂O₃ +38% SiO2 material. Mullite tube can be used up to 1650 ^oC in both oxidizing and reduce atmospheres, which has better thermo-conductivity and provides better temperature uniformity compared with quartz tube. Besides, the physical and thermal properties of mullite allow operation under fast cooling/heating.

• O.D:      2 " +/- 0.05''                   (50.8 mm)

• I.D:        1.75'' +/- 0.05''                (44.45 mm)

• Length:  12"                                (304.8 mm)

• Max. Working Temperature:         1500^oC  (without vacuum)
  Continuous Working Temperature: 1450 ^oC
