Automatic Liquid Nitrogen Grinder, -196°C (CAT#: STEM-AL-4839-ZJF)

The automatic liquid-nitrogen grinder is a laboratory sample-preparation instrument designed for ultra-low-temperature disruption of biological and material samples. It processes samples through three-dimensional bead movement inside a liquid-nitrogen-cooled chamber. The system supports a broad range of tubes, plates, and grinding jars. Operators manage the run through a dedicated 10-inch touch-screen control system. The adapter-based configuration allows the sample format to be matched to the intended workflow. Temperature management supports -196°C to 60°C monitoring with an operating chamber at -140°C to -196°C during sample processing. The instrument is suitable for preparing material before nucleic acid, protein, or compositional analysis. Automatic liquid-level sensing and replenishment maintain the programmed cryogenic condition.
