The MEDILAB Porcelain Streak Plate is a high-quality ceramic plate used to determine the streak colour of mineral samples during mineral identification. Its smooth, unglazed surface provides accurate, consistent streak results essential for academic, geological, and industrial analysis. Designed for reliable performance, it is a staple tool for laboratories, universities, field geologists, and research environments requiring precise mineral characterisation.

Key Features

• Smooth, unglazed porcelain surface for accurate streak testing.
• High hardness and scratch-resistant surface suitable for repeated mineral testing.
• Chemically inert and unaffected by common laboratory reagents.
• Durable and long-lasting plate ideal for both field and laboratory use.
• Flat, stable design ensures consistent and clear streak marks.
• Easy to clean and maintain, ensuring contamination-free results.

Material Specifications

• Material: Premium laboratory-grade porcelain.
• Thermal Properties: Withstands moderate heating; resistant to temperature shifts when handled properly.
• Chemical Resistance: Inert to most acids, alkalis, and solvents used in geological and mineral testing.
• Mechanical Properties: High density and hardness to resist scratching and wear.
• Standards: Manufactured under ISO-compliant production for dimensional and quality consistency.

Technical Specifications

• Design: Rectangular, unglazed porcelain testing plate.
• Available Sizes: Standard mineral-testing dimensions (custom sizes available on request).
• Tolerance: Precision-finished surface to ensure uniform streak quality.
• Calibration: Not required.
• Included Accessories: Supplied as a standalone streak plate.

 Handling & Precautions

• Avoid dropping or applying excessive force to prevent chipping or breakage.
• Clean gently using mild detergent and soft brushes; avoid abrasive cleaners.
• Do not expose to rapid temperature changes to prevent thermal stress.
• Use only with mineral samples suitable for streak testing (avoid excessively hard stones that may damage the plate).
• Store in a padded case or drawer to extend service life.

Applications

• Widely used in geology labs, mineralogy research, and earth science departments.
• An essential tool for identifying mineral streak colour during classification.
• Suitable for mining companies, QC/QA labs in raw materials testing, and academic institutions.
• Valuable in field surveys, classroom teaching, and professional geological analysis.
