Apparatus for collecting and dispensing liquids and for particle counting

Abstract

Abstract METHOD AND APPARATUS FOR COLLECTING ANALYTICAL SAMPLES, PARTICULARLY BLOOD SAMPLES, FOR CENTERIFUGING THESE SAMPLES AND SEPARATING THEM INTO TWO OR MORE FRACTIONS AND FOR SISPENSING THE SAMPLE OR SAMPLE FRACTION INTO TWO OR MORE ALIQUOTS COMPRISING A SAMPLE COLLECTOR IN THE FORM OF A BODY MEANS HAVING GENERALLY CENTRAL CAPILLARY TUBING WHICH IS GENERALLY SEPARABLE INTO TWO OR MORE PARTS, ONE OF WHICH CAN BE MANUALLY OF AUTOMATICALLY FITTED AS AN INTERGRAL PART OF TUBING WHICH FEED LIQUID INCLUDING SAMPLE OR SAMPLE FRACTION TO A DROP GENERATOR MEANS WHEREIN SAMPLE OR SAMPLE FRACTION IS DESPENSED INTO ONE OR MORE ALIQUOTS. MEANS ARE ALSO PROVIDED FOR INCORPORATING THIS SAMPLE DISPENSING SYSTEM IN APPARATUS FOR CHEMICAL ANALYSIS BY MOLECULAR ABSORPTION SPECTROSCOPY, MOLECULAR FLUORESENCE SPECTROSCOPY, AND OTHER ANALYTICAL TECHNIQUES. MEANS ARE ALSO PROVIDED TO ENABLE A SAMPLE TO BE DILUTED OR REACTED AS NECESSARY WITH DILUENT OR REAGENT PREFERABLY USING DROP GENERATOR MEANS AND DISPENSED AS A STREAM OF DROPS PREFERABLY OF MUCH SMALLER DIAMETER THAN THE DIAMESTER OF THE DROP GENERATOR MEANS AND PASSED THROUGH PARTICLES COUNTING AND SEPARATING MEANS FOR ACCURATE PARTICLE COUNTING AND SEPARATING.
