Crystallizing Dish

The GISCOM Crystallizing Dish is a shallow, flat-bottom glass vessel designed for crystallisation, evaporation, and sample concentration processes in scientific laboratories. Its wide surface area and excellent thermal resistance make it ideal for controlled solvent evaporation and forming pure crystalline solids. Essential in chemistry, pharmaceuticals, and research labs, it ensures reliable, repeatable results in routine and advanced applications.

Key Features

• Wide, shallow design for efficient evaporation and crystal formation.
• Manufactured from Borosilicate Glass 3.3, offering superior thermal shock resistance.
• Chemically inert surface ideal for sensitive samples and reagents.
• High clarity and transparency for easy observation of crystallisation progress.
• Thick, reinforced rim for durability and secure handling.
• Smooth, easy-to-clean surface suitable for repeated laboratory use.
• Autoclavable at 121°C for safe sterilisation.
• Resistant to acids, alkalis, solvents, and laboratory reagents.
