Qiagen Retsch Tissuelyser II Bead Mill Homogenizer

Technical Notes:

The digital display operates clearly and all keypad controls respond correctly. The lid safety interlock functions as intended: the F4 error code activates when the lid is opened, as expected, and clears immediately upon closing. The clamp locking mechanism, which secures the adapter or grinding jar sets, operates as intended. A full-range test run, from the lowest to the highest oscillation frequency setting, completed without issue. See attached video for further detail.

Model Description:

The Qiagen Retsch TissueLyser II is a high-throughput bead mill homogenizer used for simultaneous disruption of multiple biological samples, including tissue, cells, and bacteria, for downstream DNA, RNA, and protein extraction. It's a standard fixture in molecular biology, genomics, and clinical research labs requiring consistent, reproducible sample prep.

Highlights

• Processes up to 192 samples simultaneously using adapter sets
• Oscillation frequency range of 3–30 Hz for tunable disruption intensity
• Compatible with standard microcentrifuge tubes and 96-well plate formats
• Enables rapid, reproducible homogenization without cross-contamination between samples
