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.

A method displacing a fluid and simultaneously gas enriching a liquid cell culture medium with a gas. The method includes injecting a controlled volume of a gas or gas mixture into a one chamber by using a gas flow controller, the injection taking place through a gas inlet into a volume of liquid. This injection produces bubbling and agitation of the volume of liquid; a build-up of gas or gas mixture due to buoyancy in a hermetic space formed by the volume of liquid and the chamber, and a pressure increase in the chamber until a sufficient controlled pressure is reached of less than or equal to 10 bar. This increase displaces the volume of liquid by a fluid outlet connecting the volume of liquid to the exterior of the chamber. Also provided are a device implementing the method and a cell culture system in a multi-well culture plate.

Provided is a packaging container including a bag main body portion having a first surface, a second surface and an opening portion; and a tongue piece portion formed to be continuously extended from the first surface. The bag main body portion and the tongue piece portion have an aluminum vapor-deposited layer on an outside thereof, the packaging container further includes an adhesion portion which is provided on the second surface to be spaced from the opening portion; and a folded-back portion which is provided between the adhesion portion and the opening portion to fold back the tongue piece portion to the opening portion side. A length of the tongue piece portion is a, a length from the opening portion to the folded-back portion is b, and a length from the folded-back portion to the adhesion portion is c. And,
a<b+c.

The present invention relates to a method for the diagnosis of a disease comprising contacting a donor tissue section with a liquid capable of extracting an antibody from said donor tissue section and contacting said liquid with an acceptor material comprising an antigen, followed by detection of a complex comprising the antibody and the antigen, and a diagnostically useful carrier comprising a donor tissue section and an acceptor material comprising an antigen.

A container for storing a biological sample is disclosed. The container includes a housing having a closed end, an open end, and a sidewall extending therebetween defining a container interior. The container has a removable closure for enclosing the open end of the housing and a sample holder for housing a biological sample detachably connected to the closure and insertable within the container interior. A port is disposed within the closure adjacent the sample holder to allow fluid to pass therethrough into the container interior. An injection device for engaging the port may also be provided. A first fluid may be initially provided within the container interior and a second fluid may be subsequently injected by the injection device through the port into the container interior.

An apparatus for heating test water includes a test container for receiving the test water, and a heating container for installation of the test container. The heating container contains burnt lime that heats the test water when being mixed with water to be tested arranged in the heating container.

An analytical toilet comprising a bowl adapted to receive excreta; one or more conduits for transporting a sample from the bowl; one or more fluid sources in fluid connection with the one or more conduits; and one or more microfluidic chips, comprising at least one fluid inlet; at least one fluid outlet; and a sensor configured to detect at least one property of an excreta sample is disclosed.

The present invention provides methods and devices for simple, low power, automated processing of biological samples through multiple sample preparation and assay steps. The methods and devices described facilitate the point-of-care implementation of complex diagnostic assays in equipment-free, non-laboratory settings.

A cover for a drug container piston array includes a plurality of cover sections configured for positioning over the drug container piston array. Each cover section includes an elongated cover section body having an open base end and a closed capped end, and a plurality of base sections or a web positioned between the plurality of cover sections and coupled to each base end. Packaging assemblies including a cover and a piston nest are also disclosed.

The present invention is directed to a cap for a biochip storage well. The cap comprises a resilient sealant layer capable, under the application of pressure, of forming a vapour-proof seal with a line contact interface formation extending around the perimeter of a biochip storage well.

An assay assembly comprising the cap of the invention and a biochip storage is disclosed. Methods of sealing a biochip storage well using a cap of the invention are also disclosed.
