Abstract: A method and device performing the method for estimation of cell count, such as sperm cell count, is disclosed. The device may be a kit including a cartridge configured to hold fluid, such as seminal fluid, and an instrument configured to centrifuge the cartridge. The cartridge and instrument are configured such that, during operation or centrifugation, they are securely attached to each other. The cartridge has a component with a defined cross-sectional volume. The defined cross-sectional volume is used to mark the component with markings, allowing a user of the device to read the markings and estimate cell volume and, thus, concentration. Various embodiments of the device are disclosed.

Abstract: 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.
