4-Inch Porcelain Ceramic Mortar and Pestle Set (100 mm OD) — Apex Labs

The Apex Labs 4-Inch Porcelain Ceramic Mortar and Pestle Set is a versatile laboratory grinding tool designed for fine pulverization, homogenizing, and crushing of solid reagents, crystalline chemicals, and biological tissue samples. Featuring a 100 mm outer diameter and an expanded volumetric capacity (~150 mL), this set provides ample working space for medium-batch sample processing in chemical, pharmaceutical, and academic laboratories. Crafted from high-purity, high-density porcelain ceramic, the mortar features a smooth glazed outer wall paired with an unglazed, textured internal basin and matching pestle tip for optimal friction and rapid particle size reduction. Its thick-walled construction delivers high physical durability, thermal shock resistance, and complete inertia to aggressive laboratory chemicals.
