Medium-Throughput Hair Grinder, 5500 rpm (CAT#: STEM-AL-4783-ZJF)

The medium-throughput hair grinder is a laboratory sample-preparation instrument designed for rapid disruption of multiple hair 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. The dual-damping structure reduces vibration during high-speed processing.
