Medium-Throughput Sample Grinder, 16 × 2 mL (CAT#: STEM-AL-4784-ZJF)

The medium-throughput sample grinder is a laboratory sample-preparation instrument designed for grinding, disrupting, and mixing multiple tissue samples. It processes samples through shaft-driven three-dimensional figure-eight oscillation. The system supports multiple 2 mL and 5 mL tube configurations. Operators manage the run through a programmable 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. Stored programs support repeatable preparation before molecular and compositional analysis.
