PREPROCESSING DEVICE, PREPROCESSING METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM STORING PROGRAM
In a recovery device, a removing target such as a blood cell is removed from a liquid sample in a sample container using a first filter unit, and a microorganism is filtered from the liquid sample using a second filter unit. A controller causes a first switch to block a flow channel in response to a sensor detecting a bubble. A medium flows from a second connection unit of the second filter unit toward a first connection unit. Thus, the microorganism filtered by the second filter unit is recovered by a recovery container together with the medium.
PARTICLE RECOVERY DEVICE AND PARTICLE RECOVERY METHOD
A particle recovery device for recovering particles contained in a liquid sample, the particle recovery device comprising: a flow cell having a flow path through which the liquid sample flows; a density acquisition unit that acquires a density of the liquid sample; standing wave forming means that applies an ultrasonic wave into the flow path to generate a standing wave; a control unit that determines a frequency of the ultrasonic wave that generates the standing wave in the flow path based on the density acquired by the density acquisition unit and causes the standing wave forming means to apply the ultrasonic wave of the determined frequency; and recovery means that recovers particles focused in the flow path by the standing wave.
PARTICLE RECOVERY DEVICE AND PARTICLE RECOVERY METHOD
A particle recovery device for recovering particles contained in a liquid sample, the particle recovery device comprising: a flow cell having a flow path through which the liquid sample flows; standing wave generating means that applies, in the flow path, an ultrasonic wave that sweeps between a second frequency that is a frequency lower than a first frequency that is a frequency of the ultrasonic wave that generates a standing wave having a predetermined number of nodes in the flow path and a third frequency that is a frequency higher than the first frequency; and recovery means that recovers the particles focused in the flow path by the standing wave generated by the standing wave generating means.
System, apparatus and method for material preparation and/or handling
Oscillating angularly rotating a container containing a material may cause the material to be separate. Denser or heavier material may unexpectedly tend to collected relatively close to the axis of rotation, while less dense or light material may tend to collect relatively away from the axis of rotation. Oscillation along an arcuate path provides high lysing efficiency. Alternatively, a micromotor may drive an impeller removably received in a container. Lysing may be implemented in batch mode, flow-through stop or semi-batch mode, or flow-through continuous mode. Lysing particulate material may exceed material to be lysed or lysed material and/or air may be essentially eliminated from a chamber to increase lysing efficiency.
Automated sample processing, fluid distribution, and sedimentation assay
The disclosure describes methods and devices with which to process and analyze difficult chemical, biological, environmental samples including but not limited to those containing bulk solids or particulates. The disclosure includes a cartridge which contains a separation tube as well as one or more valves and cavities for receiving raw sample materials and for directing and containing various fluids or samples. The cartridge may contain a separation fluid or density medium of defined density, and structures which direct particulates toward defined regions of the cartridge. Embodiments can include a rotational device for rotating the cartridge at defined rotational rates for defined time intervals. Embodiments allowing multiple assays from a single sample are also disclosed. In some embodiments, this device is used for direct processing and chemical analysis of food, soil, blood, stool, motor oil, semen, and other samples of interest.
