This unique process uses patented high voltage pulsed power discharges to fragment. Besides the unmatched quality of liberation, this process requires no mechanical contact to the sample. The risk of contamination is therefore reduced and you are provided with the cleanest possible preparation for your valuable sample.

SELFRAG is more than just sample preparation – it opens new possibilities to your research. See the stunning advantages when compared to conventional techniques.
