Description

High Alumina Crucible, Conical Form, 50mL. High Alumina Crucible. Non-glazed, 99.7% alumina crucible. High alumina crucibles are highly refractory, meant for use in reducing and oxidizing atmospheres. It is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalis and other fluxes.

Maximum use temperature is 1750°C.
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°C/hour.
