Lark LAC-25 Alumina Crucible 25ml – 99.95% High-Purity Ceramic, 1750°C Resistant (Without Lid)

The Lark LAC-25 Alumina Crucible 25mL is a high-performance laboratory vessel designed for advanced thermal processing and chemical analysis. Constructed from 99.95% high-purity Alumina (Al2O3), this 25ml crucible is built to endure extreme temperatures up to 1750°C while maintaining exceptional structural integrity.

This U-shaped ceramic container is an essential tool for materials science, metallurgy, and high-temperature chemistry. Its superior resistance to corrosive acids and alkaline fluxes makes it the ideal choice for ash testing, sintering, and the melting of precious metals or glass.

Key Features

• Superior Thermal Capacity: Safely operates at continuous temperatures up to 1750°C.

• Ultra-High Purity (99.95%): Ensures zero contamination for sensitive chemical samples and analytical procedures.

• Outstanding Corrosion Resistance: Chemically inert to most acids, alkalis, and organic solvents.

• Exceptional Durability: High mechanical strength and wear resistance for repeated laboratory use.

• Uniform Heating: Precision-molded walls ensure consistent heat distribution across the 25ml volume.
