Agate Mortar & Pestle

GISCOM  Agate Mortar & Pestle sets are precision-crafted grinding tools made from natural, high-density Agate stone—an amorphous form of silica known for its hardness, purity, and chemical inertness. These tools are essential for finely grinding, homogenizing, and mixing samples with minimal contamination. They are widely used in laboratories where precision sample preparation is critical, particularly in pharmaceutical, chemical, and analytical workflows.

 Key Features

• Made from genuine, naturally occurring Agate stone
• Superior hardness (Mohs 6.5) for efficient grinding and reduced wear
• Highly polished, non-porous surface minimizes sample adsorption
• Chemically inert—ideal for acids, alkalis, and sensitive materials
• Ensures low contamination, preserving analytical accuracy
• Smooth pestle action for uniform, fine grinding
• Aesthetic, durable, and long-lasting laboratory tool
• Available in multiple shapes and custom designs on request

Material Specifications

• Optional Accessories: Storage cases, additional pestles, and customized shapes (hexagonal, circular, etc.)

Handling & Precautions

• Handle with care to avoid dropping or mechanical shock
• Clean with mild detergents; avoid abrasive cleaners that may scratch the surface
• Not recommended for high-temperature heating; do not autoclave
• Avoid grinding extremely hard materials that exceed the Agate hardness
• Always store in a padded box to prevent chipping
• Rinse and dry thoroughly after each use to maintain longevity

Applications

The GISCOM  Agate Mortar & Pestle is widely used in:

• Pharmaceutical labs: API grinding, formulation research
