Table 3.

Comparison between the solution volumes measured and the preset values, results are average of three measurements.

Measured volume (μL)*	Preset volume (μL)
$17.93\pm 0.06$	$17.7\pm 0.2$
$29.40\pm 0.05$	$29.3\pm 0.3$
$58.6\pm 0.7$	$58.8\pm 0.5$
$76.7\pm 0.3$	$77.7\pm 0.4$
$100.5\pm 0.6$	$99.6\pm 0.7$

*Values obtained weighting the delivered volume of water and considering the water density at 25°C.
