A sample container cap (or “cap”) is configured to be used with a sample container for collecting fluids. The cap has a body and a shutter connected to the body. The cap has a (1) first, open position in which at least one body opening and at least one shutter opening are not aligned and the cap is configured so that fluid cannot readily pass therethrough, (2) second, open position in which the at least one body opening and the at least one shutter opening are aligned and the cap is configured so that fluid can pass therethrough, and (3) third, closed and locked position, in which the at least one shutter opening and the at least one body opening are not aligned and fluid cannot readily pass through the cap, and the cap is configured to not be moved to an open position.

The present invention relates to a platelet rich plasma (PRP) extracting device and extracting method using the same, and more particularly, to a platelet rich plasma (PRP) extracting device capable of quickly and effectively extracting the highly concentrated PRP from centrifuged blood by a simple manipulation.

Provided herein are systems and methods for a point of care apparatus. The point of care apparatus includes a fluid container for receiving a biosample, an intermediate cap, and a cartridge having at least one microfluidic channel.

A microbiological testing device for testing a liquid to be analysed that is liable to contain at least one microorganism, includes a closed inner space, a microbiological filtration member and an inlet port. The device has a nutritive layer in contact with the filtration member, and in that, in a configuration for providing the device an open/close member of the inlet port is in a closed state; the absolute gas pressure inside the closed inner space is strictly less than the standard atmospheric pressure, such that the device is able to create suction through the inlet port during a first opening of the open/close member.

A piston for centrifugation according to one embodiment may include: a body; a valve which can move inside the body to the front side and the rear side of the body according to an applied external force; a fluid channel through which a fluid flows from the front side of the body to the rear side of the body; and a valve support for guiding movement of the valve.

A disposable diagnostic device includes a body having a first channel and a second channel spaced from the first channel. A shroud is operably fixed to the body and encloses a chamber which is configured in a hermetically sealed-off relation from the first and second channels when the device is in a non-activated first state and is in open communication with at least one of the first and second channels when the device is in an activated second state. A reactant and an inert gas are disposed in the chamber such that the inert gas protects the reactant from being exposed to contaminants when the device is in said non-activated first state. A method of constructing a disposable diagnostic device is also disclosed.

A top for a plasma storage container includes a top body that defines the structure of the top and seals an opening of the plasma storage container. The top also includes a first opening and a vent opening extending through the top body. A valve mechanism is located at least partially within the top body and includes an aperture therethrough. The aperture opens upon connection of a blunt cannula to provide access to the interior of the plasma storage container. The top also includes a vent filter. The vent filter allows air to vent through the vent opening during plasma collection.

Reusable network of spatially-multiplexed microfliuidic channels each including an inlet, an outlet, and a cuvette in-between. Individual channels may operationally share a main or common output channel defining the network output and optionally leading to a disposable storage volume. Alternatively, multiple channels are structured to individually lead to the storage volume. An individual cuvette is dimensioned to substantially prevent the formation of air-bubbles during the fluid sample flow through the cuvette and, therefore, to be fully filled and fully emptied. The overall channel network is configured to spatially lock the fluidic sample by pressing such sample with a second fluid against a closed to substantially immobilize it to prevent drifting due to the change in ambient conditions during the measurement. Thereafter, the fluidic sample is flushed through the now-opened valve with continually-applied pressure of the second fluid. System and method for photometric measurements of multiple fluid samples employing such network of channels.

Mercury vapor reference systems, devices, and method for testing mercury vapor analyzers. A variable volume dilution chamber such as a syringe selectively receives mercury vapor and a dilution gas to dilute the mercury vapor prior to dispensing into an airflow for testing by the mercury vapor analyzer.

The present invention relates to a microfluidic device (100) for mixing liquids, wherein the microfluidic device (100) comprises a plurality of device inlets (110), each device inlet (110) for receiving a liquid; a chamber assembly (120) comprising a set of chamber inlets (122) in fluid communication with the device inlets (110); a mixing chamber (124) for receiving the liquids through the chamber inlets (122); and a plurality of chamber outlets (126) for communicating the liquids away from the mixing chamber (124); and a set of device outlets (130) in fluid communication with the chamber outlets (126), wherein the chamber outlets (126) are spaced around the mixing chamber (124) such that the mixing chamber (124) facilitates uniform mixing of the liquids communicating from the chamber inlets (122) to the chamber outlets (126). The invention also relates to a method of additive manufacturing a product comprising the microfluidic device as well as a liquid control system for controlling liquids in a microfluidic device.
