Teardrop Plant Tissue Grinder, 3000 rpm (CAT#: STEM-AL-4802-ZJF)

The teardrop plant tissue grinder is a laboratory sample-preparation instrument designed for grinding and homogenizing plant tissues. 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. The compact DC-powered design supports both bench and mobile workflows.
