ALL LABWARE

Alumina Labware

Alumina Characteristics

99.7% alumina or more is distinguished by its good plasma resistance, high purity and wear resistance.

These wares are highly refractory, meant for use in reducing and oxidizing atmospheres. It is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalies and other fluxes. Suitable for glass melting, including borosilicate glass.

Recommended for use with refractory metals such as Molybdenum, Platinum, Rhodium, Tungsten, Tantalum and Iridium. High- Alumina Labware temperature change rate should not exceed 150 degree/hour.
