High-Temperature Alumina Crucible Set - Corundum Crucible for Lab Use - 99% Alumina Material - Combo Sale(Combo 5)

The distance between the product and the heating body (such as carbon tube, silicon molybdenum rod or heating wire, etc.) should be > 5, not used for burning carbon and iron related products. The bottom of the large crucible as far as possible not direct with the bottom of the furnace, it is recommended to use corundum foot pads and other temperature resistant substances will be elevated crucible, the formation of Gas convection, in order to extend the service life of the product. .Package Include : 1 Combo

• Constructed from 99% alumina, our high-temperature crucible set ensures exceptional durability and resistance to thermal shock, making it ideal for laboratory applications.
• devised for temperatures up to 1600℃ with a sintering temperature of 1800℃, this crucible set is perfect for high-precision experiments and material testing.
• Features a recommended temperature change rate of less than 5℃/min below 1200℃ and 4℃/min above, ensuring safe and effective thermal management during use.
• To enhance longevity, it is advised to elevate the crucible using corundum foot pads to promote Gas convection and prevent direct with furnace bottoms.
• Avoid using direct flame sources like gasoline or alcohol blowtorches; instead, opt for electric temperature control to prevent cracking and ensure even heat distribution.
