Provided herein is a pipette tip tray that includes a base and a connected pipette tip receptacle plate, where the base includes a plurality of axially-disposed base ribs disposed on two or more internal wall surfaces, the pipette receptacle plate includes a plurality of plate ribs disposed on the distal surface of the plate, and a portion of at least a subset of the plate ribs is in contact with at least a portion of an end of at least a subset of the base ribs.

An apparatus for storing blood plasma separated after fractionation from whole blood within a wrapped hematocrit (capillary) tube. The apparatus is large enough to receive and display a standard laboratory identification label. The apparatus stores plasma from a hematocrit tube that does not include thixotropic gel. The apparatus housing has an intended upright orientation, a central axis, a top end, a bottom end, and side walls defining an internal cavity. A wall with an upper surface and a lower surface divides the internal cavity into an upper cavity and a lower cavity. A reservoir is formed in the upper cavity. A removable cap seals the reservoir. The cap is movable between open and closed positions. A channel within the lower cavity extends axially from the bottom of the housing to the wall. The channel receives and supports the wrapped hematocrit tube while plasma is expelled therefrom and into the reservoir.

A system for diagnostic testing may include a meter for performing a diagnostic test on a sample applied to a test media, the meter having a housing and an interface for receiving a signal representing coding information, and a container configured to contain test media compatible with the meter, the container having a coding element associated therewith. Additionally, the system may provide a mechanism for removing the meter from an interconnected test container and reattaching it to a new container using on-container coding methods that can recalibrate the meter for the new container of test strips.

The objective of the present invention is to provide a particle detection device and a particle detection method that can individually and continuously detect a wide range of particles. The objective is achieved by a particle detection device including: a particle separation channel through which particles are separated according to particle sizes in a perpendicular direction to the flow of fluid; and two or more particle recovery channels that are connected to and branched from the particle separation channel, in which each of the particle recovery channels includes a particle detection unit that includes an aperture and an electric detector.

An analysis cartridge includes a first cover, a second cover, a plurality of containers, a plurality of fluid tunnels and a rotary valve. The second cover has two opposite surfaces, a plurality of first through holes and a second through hole individually penetrate through the two opposite surfaces, and the first cover is attached to the second cover. The plurality of containers are disposed between the first cover and the second cover, with each of the containers being aligned to and filled in the first through holes. The plurality of the fluid tunnels are disposed on the first cover, and each of which is individually connected with a first pipette. The rotary valve is rotatably disposed between the first cover and the second cover to correspond to the second through hole, and a flow channel disposed on the rotary valve is connected with the containers individually.

The present invention is directed to systems and devices that allow for separation of cells based on size and electric properties and for high-throughput cell sorting. The system may comprise a microfluidic platform having a main microfluidic channel and cavity acoustic transducers (CATs). The microfluidic platform may be coupled to an external acoustic source. The system may further comprise a fluid disposed through the main microfluidic channel comprising cells having different sizes and electric properties. The fluid may intersect the CATs to form one or more interfaces. The system may further comprise electrodes underneath the microfluidic platform. The CATs may oscillate the interfaces to produce one or more microstreaming vortices, such that each microstreaming vortex is capable of selectively trapping cells based on size. The set of electrodes may apply an AC to cause the cells to move relative to the set of electrodes based on electric properties.

A holding structure for holding a plurality of containers for pharmaceutical, medical or cosmetic purposes includes a carrier having openings or receptacles for accommodating the containers. Holding devices for holding the containers are provided at the openings or receptacles. The holding devices can selectively assume two different stable positions, namely a first stable position in which the containers can be inserted without friction into the openings or receptacles and a second stable position in which the containers are held in the respective opening or receptacle by frictional engagement or by positive locking. The containers can be reliably inserted into the openings or receptacles without material abrasion. In the open insertion position of the holding devices, a large number of containers can be inserted concurrently into the openings or receptacles without high forces acting on the holding structure.

The application relates to a sample holder (110) and a system (100). The application also relates to a method for processing a biological sample (S) and use of the sample holder or of the system in an analytical method or a diagnostic method. The sample holder (110) comprises a tubular member (111) with a wall that is at least locally transparent and at least locally permeable for reagents, wherein the tubular member consists at least partially of a transparent material.

A solid reagent containment unit is formed by a support; a frame body fixed to the support and delimiting internally, together with the support, an analysis volume; a reagent-adhesion structure within the analysis volume; and at least one reagent cavity, which extends within the reagent-adhesion structure. The reagent-adhesion structure is of an adhesion material embossable at temperatures lower by 6-8° C. than its own melting point and has a melting point such as not to interfere with the analysis. The reagent cavity forms a retention wall, laterally surrounding the reagent cavity, and houses dried reagents. The adhesion material is chosen among wax, such as paraffin, a polymer, such as polycaprolactone, a solid fat, such as cocoa butter, and a gel, such as hydrogel or organogel.

A microfluidic system is intended for the analysis of a biological sample containing biological species. The system includes an optical detection device having a source configured to emit an optical signal and at least one sensor having a capture surface defining an optical signal reading zone. The system also includes a microfluidic device having a support in which an amplification chamber, in which an amplification reaction can be carried out, is made, and having an input channel opening into the amplification chamber. The amplification chamber includes at least one first zone located in the sensor reading zone and at least one protuberance forming a recess intended to receive a compound for internal control of the amplification reaction and arranged to be located outside the sensor reading zone or configured to be opaque to said optical signal.
