List of errors for measurement methods that are presented in the studies

Method	Error expectations (%)	Reference for error expectations
Wet cell wet	5–25	Error range detected during performed measurements
Viable cell concentration	10	Typical detected error in all performed measurements is not better than the stated error and in agreement with reports in the literature [22]
Viable cell volume	16	Error propagation based on expected Viable Cell Concentration error and 2% estimated error in diameter detection that was detected during the presented and previous measurements
