Abstract: The presently disclosed subject matter relates to methods for rapid, sensitive, and high-throughput nucleic acid testing of biological samples, e.g., blood, serum, or plasma samples from donors, as well as systems capable of performing such high-throughput nucleic acid testing.

Abstract: Systems and methods for onboard pooling of samples for high-throughput analysis of the samples. Including a sample loading area for receiving a plurality of sample tubes, and a sample transport configured to continually transport individual vessels along a transport path from a sample dispense position to a sample capture and transfer position, with intermediate positions therebetween. At least one pipettor to transfer a first and second samples from the sample loading area to the sample transport and to pool the first sample and the second sample in a vessel on the sample transport to form a pooled sample. A sample transfer mechanism to capture at least a fractionated portion of the pooled sample from the vessel at the sample capture and transfer position and to transfer the at least a fractionated portion of the pooled sample for high-throughput analysis.

Abstract: Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.
