Table 4.

Repetitive determination of hydraulic properties for the same CMA/12 probe (4•2) with a 4-mm 100-kDa MWCO polyethersulfone membrane used in the solute transport measurements in Fig. 10. The collection vial apparent elevation (Δhapp) was varied at fixed perfusate flow rates (Qin). Time lapsed refers to the approximate time since the first measurement was performed.
