Centrifugal method and apparatus for isolating a substance from a mixture of substances in a sample liquid

摘要: A centrifugal rotor effects the isolation, in a sequence of steps, substance from mixture substances dissolved, suspended or dispersed sample liquid. Multiple samples are processed simultaneously by means plurality fractionation cells, each which contains series interconnected, chambered and vented compartments individual steps isolation procedure take place. Specific preferred embodiments include lysis, sedimentation, aggregation, sorption, rinsing, desorption. The specific compartment occupied liquid one its fractions at any stage process is governed speed direction rotation gravitational force. interconnections, chambers passages sized angled to prevent predetermined amounts reagent liquids overflowing compartment. Predetermined required contact delivered every cell dynamic flow distributor accepts partially aerosolized injections said reagents pipetted dosator while rotating. method using isolate deoxyribonucleic acid described. operation centrifuge can be controlled coordinated automatically.
