Effect of viscosity on the sample flow rate in passive pump driven micro-fluidic systems. Symbols represent the mean values of n=3 parallel measurements performed in the same device. The bars correspond to the standard deviation of the data. (A) Change in the sample droplet volume as function of time using samples of different viscosities (◆ 1.0 cP; □ 1.4 cP; △ 2.3 cP; ○ 4.8 cP) (B) Dependence of the volumetric flow rates on the reciprocal value of the sample viscosity (1/μ). Data points (flow rates in the first 5 s of flow) are plotted with the best fit line Q = m·1/μ.
