In India, a 50ml silica crucible is a standard laboratory item used for high-temperature applications like ashing, melting, and chemical analysis. These crucibles are typically made from pure fused silica, allowing them to withstand continuous temperatures of approximately 1050°C and short bursts up to 1300°C—significantly higher than standard porcelain.

Key Specifications

• Dimensions: Typically around 57mm diameter x 37mm height (standard low form).
• Material: 99.8% pure fused silica (quartz).
• Finish: Usually glazed both inside and outside to improve resistance to alkalis and simplify cleaning.
• Thermal Shock Resistance: Extremely low coefficient of thermal expansion, meaning they won’t crack during rapid heating or cooling.
