A liquid analyzing device includes a carrier, a driving unit, a rotating plate and a transmission mechanism. The driving unit is adapted to drive the carrier to rotate. The rotating plate is rotatably disposed on the carrier and adapted to support an analyzing cassette. The transmission mechanism is connected between the carrier and the rotating plate. When the driving unit drives the carrier to rotate to enable a rotation speed of the carrier to be changed and cross a predetermined rotation speed, the rotating plate rotates relatively to the carrier.

Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.

A blood component separator (1) includes a blood storage vessel (20) that includes a first storage part (21) and a second storage part (22), a slider (30) movable from the first storage part to the second storage part, and a flow path (40f) for communicating an inside and an outside of the storage vessel. When the slider is in the first storage part, the first storage part and the second storage part are in communication with each other. When the slider is inserted into the second storage part, a liquid-tight seal is formed between the slider and the inner peripheral surface of the second storage part and the communication between the first storage part and the second storage part is blocked by the slider. The slider is movable in the second storage part while maintaining the liquid-tight seal between the slider and the inner peripheral surface of the second storage part. As the slider enters the second storage part, the blood component in the second storage part is pushed out of the storage vessel through the flow path.

The present disclosure provides an insert for supporting a specimen within a centrifuge. The insert includes at least a base having a central aperture for receiving a receptacle and a specimen support. The specimen support is selectively coupled to the base and includes at least one aperture extending through the specimen support and in fluid communication with the receptacle.

Systems, methods and devices are provided for the automated centrifugal processing of samples. In some embodiments, an integrated fluidic processing cartridge is provided, in which a centrifugation chamber is fluidically interfaced, through a lateral surface thereof, with a microfluidic device, and wherein the integrated fluidic processing cartridge is configured to be inserted into a centrifuge for centrifugation. A cartridge interfacing assembly may be employed to interface with the integrated fluidic processing cartridge for performing various fluidic processing steps, such as controlling the flow of fluids into and out of the centrifugation chamber, and controlling the flow of fluids into the microfluidic device, and optionally for the further fluidic processing of fluids extracted to the microfluidic device. The integrated fluidic processing cartridge may include a supernatant chamber the extraction of a supernatant thereto, and a diluent chamber for diluting a suspension collected in the centrifugation chamber.

A centrifuge for cleaning a reaction vessel unit comprises a rotor and a rotor chamber in which the rotor is positioned and supported in rotary fashion. The rotor chamber is delimited by a housing having a drainage channel beneath the rotor. Adjacent to the channel, the inner surface of the housing is embodied in the form of a funnel that feeds into the channel. This centrifuge does not require a suction pump for suctioning liquids from the rotor chamber. In addition, the centrifuge can be provided with an exchangeable module that delimits the rotor chamber and includes the rotor. The exchangeable module can be exchanged after a predetermined amount of use and replaced with another. It is also possible, however, for the module to be removed from the centrifuge, cleaned, and reinserted.

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.

Disclosed is a centrifugal separation chamber (100) rotatable about an axis (AR) and having a variable volume separation space (116) therewithin and a port (102) in fluid communication with the volume for filling and emptying the volume, the chamber including a relatively rigid portion (104) proximal to the port which has walls defining a part of the volume and arranged to provide reducing dimensions of the volume toward the port, the chamber further including a flexible portion (106) distal to the port for providing said variable volume, the flexible portion including a mechanical interface (110) for transmitting movement to the flexible portion to cause said variable volume.
