Teardrop Motion Grinder, 3000 rpm (CAT#: STEM-AL-4785-ZJF)

The teardrop-motion grinder is a laboratory sample-preparation instrument designed for grinding and homogenizing tissue samples. It processes samples through a high-speed three-dimensional teardrop trajectory. The system supports wet, dry, and cryogenic grinding configurations. Operators manage the run through a 3.5-inch touch-screen interface. The adapter-based configuration allows the sample format to be matched to the intended workflow. Its closed operating arrangement helps contain grinding tubes during processing. The instrument is suitable for preparing material before nucleic acid, protein, or compositional analysis. Its motion pattern is designed to distribute bead impact throughout the sample tube.
