Antslab offers Ceramic Tube- Alumina Tubes with 99.5% Al2O3. Because high-temperature processes demand reliable components, our Alumina Tubes are most apt. Laboratory and industrial furnace applications up to 1700°C uses Alumina Tubes 99.5% and provide desired protection against the corrosive atmosphere. Likewise, it also protects the thermocouple sensors against mechanical damages.

Following are the properties of Alumina Tubes  (Ceramic Tube)

1. The high temperature is resistant.
2. Thermal shock resistant.
3. Corrosion resistant.
4. High thermal conductivity.
