My TissueLyser II sometimes fails to maintain the set frequency. What should I do?

Frequency can be set from 3–30 Hz and is kept constant by a speed controller during operation. It may vary in a range of 0.2–0.4 Hz. If you see larger variations, please make sure not to overload the sample tubes with too much starting material.

If the issue persists, please contact QIAGEN Technical Service to have a repair by QIAGEN’s Regional Repair Center.
