TABLE 1.

Assumptions for the uncertainty quantification calculations. $\mathcal{U}$ stands for uniform distribution. We distinguish between geometrical and handling uncertainties. The geometrical uncertainties are due to manufacturing inaccuracies or the limited knowledge of the exact geometry. We estimated the geometrical uncertainties of the electrodes based on a measurement of the chamber used in this work. In contrast, the handling uncertainties are introduced by the experimenter.

Parameter	Distribution	Reasoning
Geometrical uncertainties
Height of electrode h 1 or h 2/mm	$\mathcal{U}(0.01,1.5)$	Misalignment of electrodes
Length of bottom part l b/mm	$\mathcal{U}(\mathrm{21,22.3})$	Misshaping of electrodes
Spacing of electrodes d/mm	$\mathcal{U}(\mathrm{23,25})$	Misalignment of electrodes
Decay of meniscus profile c/mm	$\mathcal{U}(1.95,2.05)$	Estimate based on Schuderer and Kuster (2003)
Height of meniscus profile h 0/mm	$\mathcal{U}(1.8,2.5)$	Estimate based on Schuderer and Kuster (2003)
Handling uncertainties
Cell culture medium V/ml	$\mathcal{U}(3.4,3.6)$	Pipetting inaccuracies
