摘要： An apparatus for measuring ionic activity is comprised of a rotatable turret and at least one pair of vertically movable probes. The turret intermittently conveys slide-type ionic activity measuring devices, one by one, on each of which are spots of reference and sample solutions, to a measuring section where the probes come into contact with the measuring device so as to measure the potential difference corresponding to the difference in ionic activity of a specific ion between the reference and sample solutions. After measurement the turret further conveys the device to a discharging section where the device is automatically discharged.

摘要： An apparatus for measuring ionic activity has a nozzle connected to a reservoir containing a reference solution. The reference solution is pumped up from the reservoir without coming into contact with air, so as to be quantitatively dripped through the nozzle when a slide-type ionic activity measuring device is located at a position below the nozzle. After the reference and sample solutions are spotted on the ionic activity measuring device, at least one pair of probes comes into contact with the device so as to measure potential difference corresponding to ionic activity difference of at least one ion between the reference and sample solutions.

摘要： An ionic activity measuring device comprises ion selective electrodes, porous liquid distributing members for distributing a reference solution and a sample solution to the ion selective electrodes, a frame for housing the ion selective electrodes and the porous liquid distributing members and provided with a pair of liquid feed holes for feeding the reference solution and the sample solution to the porous liquid distributing members, and a porous bridge for achieving electrical conduction between the reference solution and the sample solution fed in drops to the liquid feed holes. The porous bridge is disposed in a recess formed in the surface of the frame so that the depth of the recess is not smaller than the height of the porous bridge. End portions of the porous liquid distributing members are protruded to regions under the liquid feed holes so that the fed solutions may enter from side faces of the end portions. The porous bridge may extend at positions deviated from centers of the liquid feed holes. The frame may be provided with holes for insertion of potential measuring probes, and air discharging holes.

摘要： In a method for mixing a small amount of a liquid sample with a second liquid, the liquid sample is first fed into a mixing vessel. Thereafter, the second liquid is discharged from an orifice of a second liquid pipette tip into the vessel, and the liquid sample and the second liquid are thereby stirred with each other. The small amount of the liquid sample is thus efficiently stirred by the second liquid and is thereby uniformly mixed with the second liquid. Also, the liquid sample and the second liquid are mixed with each other in an accurate mixing ratio.
