Crucibles, Silica, with Lid

A silica crucible with a lid is a laboratory vessel made of silica glass, designed for high-temperature applications. It's used to hold substances while they are heated, and the lid helps to contain the material, prevent contamination, and regulate temperature and airflow during heating.

Heat resistance up to 1000° C,

Material:  Silica crucibles are made from fused silica glass, a material known for its excellent thermal stability and resistance to chemical attack.

High-Temperature Use: They are designed to withstand very high temperatures, making them suitable for melting, calcination, combustion, and other high-temperature chemical reactions. 

Lid's Function: 

• Contain the substance: Prevents spillage or loss of material during heating.
• Reduce contamination: Protects the contents from external elements.
• Control atmosphere: Regulates airflow into the crucible, which can be important for certain reactions.
