Pestle

The GISCOM Porcelain Pestle is a precision-crafted grinding tool designed for effective crushing, homogenising, and pulverising of solid samples. Its unglazed grinding surface ensures optimal friction, enabling uniform particle size reduction essential for accurate laboratory analysis. Durable, autoclavable, and comfortable to handle, this pestle is ideal for daily sample preparation across research, pharmaceutical, and industrial laboratories.

 Key Features

• Unglazed grinding surface provides excellent abrasion performance.
• Oversized ergonomic design for improved grip and hand comfort during extended use.
• Dense, high-strength porcelain ensures long service life and consistent results.
• Chemically resistant exterior suitable for routine laboratory chemicals and reagents.
• Autoclavable for safe sterilisation and contamination control.
• Smooth, chip-resistant construction for reliable, repeated use.

Material Specifications

 Technical Specifications

• Available Sizes: Compatible with multiple GISCOM porcelain mortars (various diameters/volumes).
• Design: Precision-shaped pestle for optimal grinding efficiency.
• Tolerance & Quality: Uniformity maintained across production batches.
• Sterilization: Autoclavable; safe for standard lab sterilization cycles.
• Packaging: Individually packed with protective material for safe international transport.
• Accessories Included: Packed as a standalone pestle; mortar supplied separately.

 Handling & Precautions

• Use only with compatible mortars to prevent chipping or uneven friction.
• Clean with mild detergents; avoid abrasive cleaning pads.
• Prevent sudden temperature changes to avoid cracking (e.g., avoid moving from hot to cold environments).
• Do not use for extremely hard or metal-like samples that may damage the ceramic surface.
• Always dry completely before storage to maintain material integrity.

 Applications

• Suitable for pharmaceutical, chemical, biotechnology, food testing, and environmental laboratories.
• Ideal for grinding powders, tablets, crystalline materials, botanical samples, and small solid compounds.
• Used in QA/QC, R&D, teaching labs, sample preparation, and formulation studies.
• Essential for homogenization before chemical analysis, microscopy, dissolution testing, and reagent preparation.
