ABSTRACT:
This disclosure relates to a method and apparatus for forming electrical contact with an analysis slide of the potentiometric type. A probe unit, electrically connected to an electrometer, comprises a plurality of probe tips which are adapted to penetrate into the electrodes of an analysis slide and to move laterally in a direction generally parallel to the electrode layers after penetration. A means is provided for preloading the probe tips to control the force required to effect lateral movement of the tips.
