Cell Lab High-Purity Alumina (Al₂O₃) Rods [0.8–38 mm Diameter Options]

Cell Lab High-Purity Alumina (Al₂O₃) Rods [0.8–38 mm Diameter Options]

High-temperature insulating ceramic rods for precision laboratory and furnace applications

General Description

Cell Lab high-purity alumina (Al₂O₃) rods feature exceptional hardness, high melting point, low thermal expansion, and outstanding electrical insulation. With > 99 % purity and excellent chemical resistance, these rods perform reliably in high-temperature tube furnaces, thermal analysis systems, and materials research setups.

Each rod is sintered to achieve dimensional precision and mechanical strength suitable for both laboratory-scale testing and industrial R&D environments.

Note – Alumina rods are consumable products and not covered by warranty. Please inspect the items within one week of delivery; Cell Lab will only be responsible for manufacturing defects reported during this period.
