Multi-Sample Cryogenic Grinder, -50°C (CAT#: STEM-AL-4790-ZJF)

The multi-sample cryogenic grinder is a laboratory sample-preparation instrument designed for low-temperature disruption of biological and material samples. It processes samples through three-dimensional high-frequency bead movement. The system supports multiple cryogenic adapter formats. Operators manage the run through a touch-screen control system. The adapter-based configuration allows the sample format to be matched to the intended workflow. Temperature management supports -50°C to room-temperature operation during sample processing. The instrument is suitable for preparing material before nucleic acid, protein, or compositional analysis. Low-temperature processing helps limit sample heating, degradation, and agglomeration.
