To ensure consistent performance and extend the service life of Zirconia Mortar and Pestle, users should follow proper procedures for operation, cleaning, handling, and storage. These best practices are designed to minimize contamination, preserve structural integrity, and support repeatable results in laboratory settings.

• Grinding Best Practices with Zirconia Mortar and Pestle

  1. Use appropriate force based on sample hardness. Apply firm but controlled pressure when grinding high-hardness materials to avoid edge chipping. Excessive impact should be avoided to maintain surface geometry over time.
  2. Pre-condition brittle or reactive materials. For fragile substances, begin with gentle circular motion before transitioning to deeper crushing to prevent splatter or uneven particle sizes. This improves powder uniformity for subsequent analysis.
  3. Avoid overloading the mortar chamber. Keeping sample quantity under two-thirds capacity ensures proper circulation and reduces risk of contact surface abrasion. This also promotes more effective homogenization during rotational grinding.

• Cleaning and Cross-Contamination Prevention

  1. Clean immediately after each use with ethanol or distilled water. Delayed cleaning can lead to residue adhesion or chemical reactions with sample remains. Prompt removal ensures long-term corrosion resistance.
  2. Avoid metal brushes or abrasive tools. These can scratch the surface and introduce external particulates during future grinding cycles. Soft nylon brushes or lint-free wipes are recommended for daily maintenance.
  3. Conduct ultrasonic cleaning for sensitive applications. For trace-element labs, weekly ultrasonic cleaning using deionized water is advised. This helps achieve <10 ppm residual cross-contamination risk.

• Handling and Surface Protection Guidelines

  1. Do not stack or nest mortars during storage. Zirconia surfaces, while hard, can chip if edge-loaded by weight. Always store mortars individually with foam or soft padding.
  2. Avoid direct contact with metal surfaces or tools. Scratching or microfracturing may occur when struck by steel tongs or shelves. Handling with gloves or rubber grips is recommended.
  3. Inspect for wear periodically. Check pestle curvature and inner wall integrity every 200–300 cycles. Early identification of surface damage helps maintain grinding precision and powder consistency.

• Storage and Environmental Conditions

  1. Store in dry, temperature-stable environments. Relative humidity should remain below 65% to avoid potential micro-expansion during thermal shifts. Avoid placing near furnaces or windows.
  2. Keep separate from acidic or volatile substances. Though chemically inert, long exposure to fume-rich areas may gradually dull polish or affect long-term surface finish. Enclosed cabinets are preferred.
  3. Label and track units for batch control. In labs with multiple identical units, assigning codes or QR labels supports usage traceability and cleaning schedules. This is essential for GMP and ISO compliance.
