A common cause of this is that an insufficient volume of lyzate mixture has been
loaded into the cassette. Load a new cassette and repeat the ana lysis.

NucleoCounter. Then the instrument cannot press the piston down and the error
occurs. Take out the cassette, insert it properly and run the analysis.
