The present technology provides a technology capable of performing stable liquid feeding. For this, the present technology provides a cell sample liquid feeding bag or the like including at least: an outflow port from which cell sample liquid flows out; a bottom portion including a reservoir unit capable of reserving cells and at least partly including a slope; and a first inner tube extending from the outflow port toward the reservoir unit to a position not contacting the reservoir unit, and the cell sample liquid is fed from a reservoir unit side toward an outflow port side of the first inner tube.

A flexible, integrated, urine-based diagnostic device designed such that one or more diagnostic channels are integrated into the body of the device. Each diagnostic channel is designed to contain an immunoassay to detect the presence of a selected analyte so that the device can return a visible readout indicating the presence of the analyte. The flexibility of the device aids the user in the sample collection process.

A computerized device provides microscopy and electrochemistry tests, performed in dual channels. The device can be brought to the field, for on-site testing with instant results. The dual channels include an imaging channel and a signal channel.

Computerized devices provide microscopy and electrochemistry tests, performed in dual channels. The devices can be brought to the field, for on-site testing with instant results. The dual channels include an imaging (optical or microscopic) channel and a signal channel. Microfluidic chips are disclosed for use with the microscopy channel optics.

A sample holding device and related method designed to facilitate inexpensive and reliable testing of materials or specimens with beam diffraction and scattering techniques. The device features a sample receptacle that is made out of a polymer, cellulose, polymeric material, or cellulosic material. The flexible nature and low melting point of the sample receptacle allows for reliable sealing against the vacuum or gaseous environment used for beam diffraction or scattering analysis. The sample holding device can be considered disposable because of its low cost, eliminating the need for complex or unreliable cleaning procedures.

Apparatus and methods for separating blood components are disclosed in which an apparatus for separating blood generally includes a tube defining a channel and configured for receiving a quantity of blood and a float contained within the tube and having a density which is predefined so that the float is maintained at equilibrium between a first layer formed from a first fractional component of the blood and a second layer formed from a second fractional component of the blood. Upon completion of the centrifugation, the first layer may be removed from the tube while the float isolates the second layer from the first layer.

A consistent and repeatable thawing method of frozen samples in a bag-format storage vessel is described herein. Methods and systems may allow for multiple bag-format storage vessel sizes to be used in the same device. A subset of a plurality of sensors may be qualified for the thawing method. The method may further include heating a frozen sample using a first heater bank and a second heater bank. In addition, the method may include measuring a plurality of second temperatures of the bag-format vessel. At or slightly after a second threshold temperature, the method may include heating using the first heater bank and terminating heating using the second heater bank. The method may include terminating the heating of the partially thawed sample using the first heater bank after the partially thawed sample has been heated using the first heater bank for a duration.

An apparatus is disclosed having a first layer coupled to a second layer via a plurality of seals to define a storage volume that is separable by at least one intermediate seal into a first volume and a second volume. The intermediate seal is applicable after a material is introduced into the storage volume storage. The apparatus includes a first opening into the storage volume and a second opening into the storage volume. The first opening and the second opening are positioned near opposite edges. The apparatus also includes a first frangible region positioned along the intermediate seal and configured for separation of the first volume and the second volume.

A soft and stretchable microelectrode array (sMEA) including a first circuit board having a first though hole; a second circuit board having a second through hole; a microelectrode array including a plurality of microelectrodes embedded in an elastomeric substrate, wherein the microelectrode array is disposed between the first and second printed circuit boards, and includes an exposed portion corresponding the first and second through holes; a plurality of contact pads formed on a top or bottom surface of the first printed circuit board and electrically connected to the plurality of microelectrodes; and a culture well mounted on the first printed circuit board and encompassing the first through hole. Further, the exposed portion of the microelectrode array includes a 3D pocket lined with stretched microelectrodes for electrically stimulating and recording signals from an organoid placed in the 3D pocket.

The disclosure relates to a sampling system for processing a liquid sample, including a retrieving module configured to be fluidically connected to a liquid-source and configured to retrieve a liquid sample from the liquid-source, a filling module configured to fill the retrieved liquid sample into a sampling container, a storing module configured to store the sampling container filled with the liquid sample, and a disposal module configured to discard the liquid sample.
