High Alumina Crucible, Tall Form, 20mL, Each

Tall form, high alumina 20mL 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.

Properties of High Alumina Products United Scientific's high alumina wares are made of 99.7% pure aluminum oxide. Highly resistant to chemical attack, this alumina-ceramic ware is especially useful to chemists, metallurgists and others involved in high temperature work demanding contamination-free results.
