ABSTRACT:
A capillary transport device is disclosed, suitable for use as an ion bridge for potentiometric test elements. Such device has an internal capillary transport passage, and two access apertures for separate access of two different liquids to two spaced-apart regions of the passage. To control the liquid flow rate within the passage, there is disposed on at least a portion of at least one of the surfaces of the passage between the two regions, means for (a) increasing the viscosity of the liquid while it is flowing past at least one surface, and (b) at the same time maintaining such flow continuous within the passage.
