Mullite tube is made in the USA with 60% Al2O3 +38% SiO2 material. Mullite tube can be used up to temperatures to 1650 oC in both oxidizing and reduce atmospheres, which has better thermo-conductivity and provides better temperature uniformity compared with quartz tube O.D: 3.22" +/- 0.05 (82 mm) I.D: 2 7/8 (73.02 mm) Length: 48" (1200 mm) Max. Working Temperature: 1500oC (without vacuum) Continuous Working Temperature: 1450oC Fit and replace tube for MTI OTF-1200X-3 3" tube furnace. Note: This tube is ONLY capable for 80 - 82 mm Dia Vacuum Flange - FL-82. Never use other sizes of flanges on this tube.

In order get longer tube service life, Please use quartz or alumina crucible to carry sample, instead loading sample directly inside tube, please click picture below to choose one crucible boat: Inspect your delivery:Please check package for damages before accepting delivery. Should damages found, please keep all packaging materials, take pictures, and report immediately to carrier/MTI.
