Lark LAC-100 Alumina Crucible 100ml | 1750°C Heavy Duty

The Lark LAC-100 Alumina Crucible 100ml is a high-capacity, heavy-duty vessel designed for demanding thermal applications in industrial and research laboratories. Boasting a 99.95% high-purity Alumina ($Al_2O_3$) composition, this 100ml crucible provides maximum resistance to chemical flux, oxidation, and extreme temperatures up to 1750°C. Its robust, thick-walled design is specifically engineered for “Heavy Duty” cycles, including high-volume sintering, melting, and calcination. With nearly zero porosity, the LAC-100 ensures that your samples remain uncontaminated even during prolonged exposure to intense heat.

Note: This heavy-duty model is supplied without a lid.

Key Features

• Industrial-Grade Purity: 99.95% Alumina content minimizes interference in sensitive chemical processes.

• Superior Heat Resistance: Engineered for stability at continuous temperatures up to 1750°C.

• Heavy-Duty Build: Reinforced wall structure for improved durability during repeated high-temperature cycles.

• Corrosion Resistance: Highly resistant to aggressive chemical environments, including molten metals and strong acids.

• Low Porosity: Dense ceramic finish prevents sample absorption and simplifies cleaning.

Technical Specifications

Primary Applications

1. Industrial Sintering: High-temperature processing of technical ceramics and advanced materials.

2. Metallurgical Melting: Smelting precious metals and alloys requiring a carbon-free environment.

3. High-Volume Ashing: Large-scale determination of ash content in geological or food samples.

4. Glass Research: Testing of glass formulations and high-temperature fusion studies.

5. Calcination: Ideal for industrial decomposition of carbonates and other inorganic compounds.

Crucible Care Guidelines

• Thermal Ramp: To ensure longevity, use a gradual heating/cooling rate (max 5°C per minute).

• Loading: Avoid packing materials too tightly to allow for thermal expansion of the sample.

• Handling: Use high-temperature tongs with protective tips to prevent mechanical stress on the ceramic walls.
