Patent number: 10208340Abstract: A random access, high-throughput system and method for preparing a biological sample for polymerase chain reaction (PCR) testing are disclosed. The system includes a nucleic acid isolation/purification apparatus and a PCR apparatus. The nucleic acid isolation/purification apparatus magnetically captures nucleic acid (NA) solids from the biological sample and then suspends the NA in elution buffer solution. The PCR testing apparatus provides multiple cycles of the denaturing, annealing, and elongating thermal cycles. More particularly, the PCR testing apparatus includes a multi-vessel thermal cycler array that has a plurality of single-vessel thermal cyclers that is each individually-thermally-controllable so that adjacent single-vessel thermal cyclers can be heated or cooled to different temperatures corresponding to the different thermal cycles of the respective PCR testing process.Type: GrantFiled: December 20, 2017Date of Patent: February 19, 2019Assignee: Siemens Healthcare Diagnostics Inc.Inventors: Robert Adolfsen, Nicolae Dumitrescu, Michael Avdenko, Dario Svenjak

Patent number: 6872571Abstract: A method and apparatus for controlling a stream of liquid and air segments wherein the liquid and air segments are selectively aspirated into a first fluid conduit in a plurality of cycles, each cycle beginning with the aspiration of a first air segment and ending with the aspiration of a final air segment. The liquid and air segments are then transferred from the first fluid conduit to a second fluid conduit. The volume of the final air segment of each cycle is then adjusted after the final air segment has moved into the second fluid conduit. Next, the liquid segments and the air segments of each cycle are transferred from the second fluid conduit to a third fluid conduit. The volume of the first air segment of each cycle is then adjusted after the first air segment has moved into the third fluid conduit.Type: GrantFiled: April 3, 2000Date of Patent: March 29, 2005Assignee: Bayer CorporationInventors: Robert Adolfsen, Paul Gherson, David Lightbody
