Hydraulic property estimates for the CMA/12 probe (4•1) used in the fluid transport model validation measurements (Figs. 5 and 6) and solute transport measurements in Fig. 11. The 100-kDa MWCO polyethersulfone membrane was 4-mm in length. Both perfusate flow rate (Q_in) and collection vial apparent elevation (Δh_app) variations were employed to alter the ultrafiltration factor. The hydraulic properties are effluent resistance (ℜ_eff), and membrane hydraulic (H_m) and Darcy (κ_m) conductivities.
