Multi-Sample Cryogenic Grinder Wonbio-E, -50°C (CAT#: STEM-AL-4791-ZJF)

The multi-sample cryogenic grinder is a laboratory sample-preparation instrument designed for low-temperature grinding, disruption, and mixing of heat-sensitive samples. It processes samples through combined vertical and lateral three-dimensional motion. The system supports tube formats from 2 mL to 50 mL. Operators manage the run through a dedicated LCD 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. The configuration supports sample preparation before DNA, RNA, protein, and compositional analysis.
