ST-M51 Online Cryogenic Grinder, -55 to 37 °C (CAT#: STEM-AL-3577-ZJF)

ST-M51 is an online cryogenic grinder designed for rapid preparation of biological and temperature-sensitive samples. Vertical high-frequency movement drives grinding balls through repeated impact and friction. The process supports grinding, mixing, homogenization, and cell disruption. An integrated cooling system regulates the working chamber during preparation. Temperature control helps preserve heat-sensitive and volatile sample properties. Multiple adapters accommodate tubes, vials, and deep-well plate formats. Automatic lid handling and center-position locking support consistent loading. Programmable controls allow grinding time and repeated cycles to be selected. The system supports controlled dry, wet, and cryogenic workflows within the stated ranges.
