Rotor having sample holding means

Abstract

Abstract CAVITY TO THE CUVETTE UPON ROTATION OF THE DISK WHILE PREVENTING SUCH TRANSFER OR RETURN OF FLUIDS UNDER STATIC CONDITIONS. AN OPENING IS PROVIDED THROUGH EACH BARRIER TO ENHANCE MIXING IN THE CUVETTES. A VACUUM ACTIVATED DRAINLINE EXTENDS RADIALLY INWARD FROM A POINT ADJACENT THE RADIAL EXTREMITY OF EACH CUVETTE TO A VACUUM SOURCE FOR REMOVING OVERLAYING LIQUID FROM THE CUVETTES. A CENTRAL RECEIVING AND DISTRIBUTION CHAMBER BORDERED BY SEGMENTATION SERRATIONS IS IN FLUIDS COMMUNICATION WITH EACH LOADING CAVITY TO FACILITATE DYNAMIC OR STATIC LOADING OF THOSE CAVITIES. A FAST PHOTOMETRIC ANALYZER OF THE MULTISTATION, ROTARY TYPE IS PROVIDED WHICH IS SUITABLE FOR PERFORMING SAMPLE AND REAGENT DIVISION, MIXING, SEDIMENTATION, WASHING, TRANSFER, AND LIGHT ABSORBANCY FUNCTIONS. TWO SETS OF CAVITIES ARE DISPOSED IN CONCENTRIC ANNULAR ARRAYS WITHIN A DISK ADAPTED TO ROTATE ABOUT ITS CENTRAL AXIS. THE RADIALLY OUTER SET OF CAVITIES CONSTITUTES A ROTARY SYSTEM OF CUVETTES SUITABLE FOR PHOTOMETRIC MEASUREMENTS. CAVITIES IN THE RADIALLY INNER SET OF CAVITIES, HEREIN DESIGNATED LOADING CAVITIES, COMMUNICATE, ON A ONE-TOONE BASIS, WITH RESPECTIVE CUVETTE CAVITIES. A SLOPING BARRIER IS PROVIDED BETWEEN EACH LOADING CAVITY AND CORRESPONDING CUVETTE TO ALLOW FOR CENTRIFUGAL TRANSFER OF FLUIDS FORM THE LOADING
