CRUCIBLE (Tall Form with Lid)

The GISCOM Porcelain Crucible (Tall Form with Lid) is a high-temperature laboratory vessel designed for heating, calcining, ignition, and ashing of samples with accuracy and reliability. Its tall-form profile provides greater volume and improved thermal distribution, making it essential for analytical chemistry, gravimetric analysis, and material testing. Engineered for consistent performance, this crucible ensures precise results in academic, industrial, and research environments.

Key Features

• High-temperature resistant porcelain, ideal for ignition and ashing procedures
• Tall-form design enabling increased sample capacity and uniform heating
• Glazed inside and outside (except rim and bottom) for chemical resistance and easy cleaning
• Smooth, non-porous surface minimising contamination and sample adhesion
• Matching porcelain lid ensures controlled heating and minimises material loss
• Thermally stable, suitable for repeated heating–cooling cycles
• Strong mechanical strength and high durability under laboratory conditions
• Resistant to acids, alkalis, and most laboratory reagents

Material Specifications

• Material: High-grade laboratory porcelain
• Thermal Properties: Withstands temperatures up to 1000–1200°C (typical porcelain firing range). Excellent thermal shock resistance under controlled heating
• Chemical Resistance: Highly resistant to corrosive chemicals, solvents, and thermal decomposition products
• Mechanical Strength: Dense, vitrified porcelain delivering durability and long service life
• Quality Standards: Manufactured under ISO 9001:2015 quality management compliance

 Technical Specifications

• Available Capacities: Multiple sizes suitable for analytical and industrial requirements (on request)
• Form: Tall form with matching porcelain lid
• Surface Finish: Fully glazed interior and exterior except for the outer bottom and rim
• Tolerance: Precision-moulded to ensure consistent wall thickness and thermal performance
• Accessories Included: Matching fitted porcelain lid

 Handling & Precautions

• Preheat slowly to avoid thermal shock before high-temperature use
• Allow the crucible to cool gradually on a heat-resistant surface—avoid sudden cooling
• Clean using mild detergents; avoid abrasive materials that may damage glaze
• Do not expose to direct burner flame without proper support
• Avoid rapid temperature changes that could crack porcelain
• Store carefully to prevent chipping of edges and rims

Applications

• Gravimetric analysis in academic and research laboratories
• Ignition and ashing of organic and inorganic samples
• Material testing in industrial labs, metallurgy, and ceramics
• Pharma QC/QA for residue and loss-on-ignition tests
• Chemical analysis requires stable, contamination-free sample processing
• Suitable for universities, research institutes, environmental labs, and industrial R&D
