Abstract: Embodiments are described for treating a fluid, e.g., a biological fluid. The embodiments may include systems, apparatuses, and methods. Embodiments may provide for a flow cell, with a plurality of manipulation elements, through which a fluid is flowed.

Abstract: An apparatus for manipulating magnetic particles includes a latch mechanism. The latch mechanism has a pivoting part provided on a door and an engaging part provided on a main body. In the apparatus for manipulating magnetic particles, a first contact portion of a latch engages with the engaging part at a contact point in a state that the door is closed. The contact point is located more outside of the main body than the pivot axis. Accordingly, in a case where an external force is applied to the door in a direction to open the door in a state that the door is closed, a force is applied from the engaging part to the first contact portion, thereby generating a rotational force in a C direction to the pivoting part. As a result, in the state that the door is closed, it is possible to suppress the door from being opened without a manipulation by the user.

Abstract: A system and method for lysing of whole blood for CO-Ox measurement uses a lysing chamber for acoustic lysing of whole blood in a module in which the lysing chamber is separate from a CO-Ox measurement chamber. The disclosed acoustic lysing system and method avoids the expense and complexity of chemical lysing methods and allows the whole blood sample to be lysed while under continuous flow through the lysing chamber. The acoustic lysing chamber is provided upstream from a CO-Ox measurement chamber. The separation of the lysing chamber from the Co-Ox measurement chamber provides freedom to arrange and orient various optical components and/or other CO-Ox measuring components around the CO-Ox measurement chamber. The decoupling of the lysing chamber from the CO-Ox measurement chamber allows for more efficient design of the ultrasonic lysing transducer and CO-Ox measurement optics.
