Portable Hair Grinder, 2 × 5 mL (CAT#: STEM-AL-4781-ZJF)

The portable hair grinder is a laboratory sample-preparation instrument designed for disrupting and mixing hair samples. It processes samples through a three-dimensional figure-eight bead motion. The system supports wet and dry grinding in two 5 mL tubes. Operators manage the run through an LCD control 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 portable form supports preparation work outside a conventional laboratory.
