Abstract: AN APPARATUS FOR BATCH ANALYSIS OF LIQUID SAMPLES WHEREIN SYRINGES ARE EMPLOED FOR DELIVERING REPEATABLE VOLUMES OF REAGENT TO A CELL PRIOR TO THE ADDITION OF A SAMPLE AND FOR WITHDRAWING LIQUID FROM THE CELLA AFTER ANALYSIS THEREOF. SENSING MEANS, SUCH AS A POLAROGRAPHIC OXYGEN SENSOR, IS MOUNTED IN THE SIDE WALL OF THE CELL WITH ITS SENSING CONTACTING THE LIQUID THEREIN. A STIRRING ELEMENT IS POSITIONED WITHIN THE CELL AND ROTATED ABOUT THE VERTICAL AXIS OF THE CELL SO THAT A HIGH TANGENTIAL STIRRING FORCE IS PRODUCED TO PROMOTE MIXING OF SAMPLE WITH REAGENT AND TO OPTIMIZE SENSOR PERFORMANCE, YET ONLY SMALL SAMPLE VOLUMES ARE REQUIRED. THE APPARATUS IS PARTICULARLY SUITED FOR RATE SENSING BATCH ANALYSIS OF BIOLOGICAL FLUIDS SUCH AS BLOOD OR URINE.
