Large-Capacity Grinder G, 20 L (CAT#: STEM-AL-4846-ZJF)

The large-capacity grinder is a laboratory sample-preparation instrument designed for processing high-volume or high-mass samples. It processes samples through combined vertical and fore-aft movement that drives grinding media in three dimensions. The system supports adapters ranging from tube arrays to 20 L vessels. Operators manage the run through an LCD operating display. 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. An electric clamping device detects the sample-container position and applies the holding force.
