Hydraulic properties of six CMA/12 probes with 3-mm 100-kDa MWCO polyethersulfone membranes obtained by varying the collection vial apparent elevation (Δh_app) at a fixed perfusate flow rate of Q_in = 1 μL/min. Values for the probe downstream internal resistance, ℜ_int, were obtained from Eq. (78) and the estimates for the effluent resistance, ℜ_eff, together with the resistance in the outflow tubing at 23.5°C, ℜ_out = 15.4cmH₂O · min/mL, calculated from Eq. (79).
