The present invention relates to a sample container having a new structure to effectively transfer a sample. A sample container according to the present invention includes: a container main body 10 that is formed in a cup shape having an open top surface, and a coupling hole 11 opened in a vertical direction is formed on one side of the container main body 10; a closed and sealed cover 20 that is coupled to an upper end of the container main body 10 to close and seal the container main body 10; and a detachably coupled collection tube 30 that is formed in the shape of a tube that extends in a vertical direction while having an open top surface, and is detachably coupled to the coupling hole 11, wherein a slope 12 that is inclined downward to the inside of the container main body 10 is formed on one side of an external circumferential surface of the container main body 10, wherein a recess portion 13 of which a lower end is open, and the recess portion 13 is formed on one side of the external circumferential surface of the container main body 10, and wherein the coupling hole 11 is formed to penetrate top and bottom surfaces of the recess portion 13, and the coupling hole 11 is formed on the top surface of the recess portion 13, accordingly, there is a merit that, after containing urine in the container main body 10 and combining the closed and sealed cover 20, the container main body 10 can be tilted to easily transfer urine to the collection tube 30 and the urine can be prevented from outflowing and contaminating the surrounding area, being contaminated, or being mistakenly switched.

A microfluidic system can include a substrate comprising an elastic material and defining a microfluidic channel. The substrate can have a first set of dimensions defining a thickness of a wall of the microfluidic channel and a second set of dimensions defining a width of the microfluidic channel. A transducer can be mechanically coupled with the substrate. The transducer can be operated at a predetermined frequency different from a primary thickness resonant frequency of the transducer. A thickness and a width of the transducer can be selected based on the first set of dimensions defining the thickness of the wall of the microfluidic channel and the second set of dimensions defining the width of the microfluidic channel.

A method for providing quantitative information for targets and a device using the same according to an exemplary embodiment of the present disclosure are provided. A quantitative information providing method for targets according to the exemplary embodiment of the present disclosure includes flowing a plurality of microdroplets into a chamber or a channel including a detection region acquiring a single layer of microdroplets in which the plurality of microdroplets is present as a single layer, and providing quantitative data of targets based on the single layer image of the microdroplets, and the detection region has a height which is one time to about two times of a diameter of the plurality of microdroplets and is defined as a region in which the plurality of microdroplets is dispersed in a plurality of columns to fill the detection region.

Described herein are cassettes and methods for using these cassettes for cryopreserving biomaterials (e.g., a bioengineered construct or natural tissue sample) by vitrification while reducing or preventing the loss of viability associated with conventional preservation methods.

The present invention relates to a tube for collecting specimens. The tube includes a tubular body having an inner surface which defines a hollow space for carrying a carrier solution or the like. The tube also includes a plurality of ridges projecting inwardly from the inner surface for engagement with at least a portion of a specimen collection tool for facilitating release of at least some of specimens therefrom.

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.
