PURPOSE:To obtain an ion activity measuring apparatus which enables a stable spotting of a reference liquid by penetrating a liquid reservoir into nozzle to drop the reference liquid on a slide at a constant amount from the nozzle. CONSTITUTION:Slides stacked in a slide holder 11A are pushed out with a pushing member 11B one at a time and forced into a slide receiving section 13A of a turret 13A with a forcing member 11E. A reference liquid in a liquid reservoir 12A is fed one drop at a time from a nozzle 12C communicating therewith 12A with the driving of a motor 12D for a peristaltic pump 12B to be spotted into one spotting hole on a slide and likewise, a liquid to be inspected is spotted into the other. The turret 13A rotates intermittently sliding over a temperature control plate 13C to measure a potential difference with a vertically movable probe 14A and is discharged through a discharge chute 15A. Thus, an ion activity measuring apparatus is obtained which enables a stable spotting of the reference liquid. |
