The High-Purity Silica Crucible Silica Crucible 25mL is a specialized laboratory melting pot engineered for high-temperature chemical reactions and sample analysis. Fabricated from 99.6% pure fused silica (SiO₂), this crucible offers exceptional thermal shock resistance, allowing it to withstand rapid temperature changes without cracking. Its high-purity composition ensures it remains chemically inert to most acids and reagents, preventing sample contamination during critical fusion or ashing processes. The 900°C rating makes it a versatile tool for routine laboratory heating and metallurgical research.

Key Features

• Exceptional Heat Resistance: Rated for continuous use up to 900°C, with a softening point near 1700°C.

• Superior Chemical Purity: Made from optimum-grade silica tubing to ensure non-reactive performance with molten metals and acidic fluxes.

• Thermal Shock Stability: Designed to move directly from high-heat environments to room temperature without structural failure.

• Uniform Wall Thickness: Precision-molded for even heat distribution, ensuring consistent results in quantitative gravimetric analysis.

• Translucent Finish: The high-polish translucent material allows for easy monitoring of reactions and clean material release.
