CRUCIBLE (Wide Form with Lid)

The GISCOM  Porcelain Crucible (Wide Form with Lid) is a durable, high-temperature vessel designed for analytical and industrial heating applications. Its wide-form geometry provides a larger surface area, making it ideal for evaporation, ash determination, material testing, and thermal decomposition studies. Engineered for consistent performance, this crucible ensures uniform heat distribution and reliable results for laboratories, universities, and industrial testing facilities.

 Key Features

• Wide-form design allowing faster evaporation and easy sample handling
• High-temperature resistant porcelain, suitable for ignition, ashing, and calcination
• Fully glazed interior and exterior (except rim and bottom) for superior chemical resistance
• Smooth, vitrified surface preventing contamination and making cleaning effortless
• Matching porcelain lid for controlled heating and reduced sample loss
• Excellent thermal shock resistance when used with standard heating protocols
• Strong mechanical strength for long service life in demanding lab environments
• Compatible with furnaces, muffle furnaces, and hot plates

Material Specifications

• Form: Wide form with fitted porcelain lid
• Surface Finish: Glazed inside and outside except for the rim and base
• Dimensional Tolerance: Precision-molded with consistent wall thickness
• Accessories Included: Matching lid supplied with each crucible

Handling & Precautions

• Heat gradually to prevent thermal shock and extend lifespan
• Allow to cool naturally; avoid quenching or sudden temperature changes
• Clean using non-abrasive cleaners; avoid strong mechanical scrubbing
• Do not expose to direct flame without proper support or a heating stage
• Store carefully to prevent chipping of rims and edges
• Use within recommended temperature limits for optimal performance

 Applications

• Analytical chemistry: evaporation, ash determination, gravimetric analysis
• Pharmaceutical QC/QA: residue analysis, LOI (Loss on Ignition) testing
• Chemical and industrial labs: heating, melting, and high-temperature sample processing
• Environmental laboratories: soil, residue, and waste analysis
• Academic institutions and research centers for routine and specialized experiments
• Ideal for pharma, biotech, chemistry, metallurgy, cement, and material science workflows
