3-Inch Black Agate Mortar and Pestle Set (75mm ID) – High-Purity Grinding Tool
The Apex Labs 3-Inch Black Agate Mortar and Pestle Set is a premium-grade laboratory specimen preparation instrument engineered for contamination-sensitive analytical applications. Carved from a naturally occurring, high-density Brazilian agate stone, this set features exceptional hardness (6.5–7.0 Mohs) and zero porosity, preventing sample absorption, cross-contamination, and mechanical abrasion loss during intensive grinding. Featuring a highly polished 75 mm inner bowl diameter, this set is tailored for spectroscopic preparation (FTIR, KBr pellet mixing), trace elemental analysis, pharmaceutical compounding, and fine micro-sample pulverization.

Technical Material & Performance Highlights
- Zero Contamination Risk: Mohs 7 hardness prevents pestle shedding and sample pollution during grinding.
- High Recovery Yields: Ultra-smooth polished surface prevents sample particles from trapping in micro-cavities.
- Chemically Unreactive: Completely inert matrix guarantees pure sample preparation for analytical instrumentation.
- Heavy Octagonal Base: Low center of gravity prevents tipping and slipping during manual operation.
Primary Sector Applications
- Spectroscopy & FTIR Sample Prep: Mixing sample matrix powders with KBr for pellet preparation.
- Trace Elemental Analysis: Non-contaminating sample preparation for AAS, ICP-MS, and XRF testing.
- Pharmaceutical & Nanotechnology: Precision pulverization of active pharmaceutical ingredients (APIs).
- Geological & Mineral Testing: Fine micro-grinding of hard mineral samples, ores, and advanced ceramics.
