ST-M200 High-Throughput Tissue Grinder, 192 Samples (CAT#: STEM-AL-3574-ZJF)

ST-M200 is a vibratory tissue grinder designed for rapid preparation of multiple laboratory samples. It handles biological tissues and a broad range of hard, soft, brittle, elastic, and fibrous materials. High-frequency movement drives grinding balls to impact and rub samples inside closed containers. The same motion supports grinding, mixing, homogenization, and cell disruption. Multi-position adapters allow tubes or wells to be processed in parallel. Dry, wet, and cryogenic workflows can be selected according to sample properties. Adjustable time and vibration settings support repeatable sample preparation. A centering and locking arrangement stabilizes the adapter during operation. The system is suited to tissue processing and extraction workflows within the specified operating ranges.
