Comparison of normalized oxygen concentration and MSS in the COC microfluidic device during HEP culture for two cases with different injection rising times. For one case, it is assumed that $T_{\mathrm{i},\mathrm{r}}=T_{\mathrm{i},\mathrm{s}}=5\min$ and $T_{\mathrm{i},\mathrm{c}}=1\min$ ($C^{\ast }$: Black solid line and ${\tau }_{\mathit{max}}^{\ast }$: Blue solid line). For the other case, $T_{\mathrm{i},\mathrm{r}}=T_{\mathrm{i},\mathrm{s}}=1\min$ and $T_{\mathrm{i},\mathrm{c}}=10\min$ are considered ($C^{\ast }$: Black dash line and ${\tau }_{\mathit{max}}^{\ast }$: Blue dashed line)
