In one configuration, a handheld compound tester to process and detect presence of a compound in a tablet is disclosed. The handheld compound tester may include a sampling chamber configured to receive a tablet and a lid couplable with the sampling chamber. The coupling of the lid with the sampling chamber may cause cutting of the tablet. A liquid may be added inside the sampling chamber to create a mixture with segments of the tablet. The mixture may be then received by a housing adjoining the sampling chamber. A test strip disposed within the housing, upon contacting the mixture, may be configured to indicate a presence of the compound in the mixture.

A hand-held applicator (10) for collecting, mixing, diluting and discharging a sample liquid, comprising a main body (20) having an inlet-aperture (24), an outlet-aperture (26) and a chamber (22) for storing a liquid solution, wherein the chamber is connected to the inlet-aperture and the outlet-aperture, a lid (12) for covering the inlet-aperture and a tube (40), moveably supported in the inlet-aperture when the lid is covering the upper portion of the main body, wherein the tube (40) is moveable between a predetermined position outside the chamber and a position, in which the tube is at least partly located in the chamber.

A microfluidic device is disclosed which comprises a main flow channel and a partition chamber connected to a portion of same by a chamber inlet and chamber outlet. The device utilizes select cross sections to advantage capillary effects during filling and partitioning steps to isolate biological or other samples in the partition chamber for analysis and can be employed in a digital array.

The invention relates to a piezoelectric micropipette, which comprises a capillary tube forming the pipette, and an expansion chamber connected to the capillary tube, the expansion chamber having a flexible element and being connected to a piezoelectric actuator. According to the invention the flexible element of the micropipette is arranged in the expansion chamber, and the flexible element is connected to a rigid displacing element, and a piezoelectric actuator is connected to the rigid displacing element.

A point of use analyzer includes pump, valve, port, and storage channel. The storage channel may hold multiple assay packets composed of reagent aliquots separated by bounding slugs. The storage channel may define an elongated lumen having two ends with each of the ends coupled to the valve. A sampling device for use with the analyzer engages the port and may include a recurrent coaxial tube having a separation medium. A method of using the analyzer with the sampling device includes steps of pumping a fluid to displace a sample into the separation medium and out through the opposed connection.

Analytical assay reaction cartridges are disclosed that include a reagent tray containing a liquid reagent disposed therein and a flexible cover removably attached thereto. The flexible cover has a portion that extends beyond the reagent tray and that forms a tab portion extends through an opening in a lid member of the cartridge in order to facilitate removal of at least a portion of the cover and release of the liquid reagent. Also disclosed are analytical assay reaction kits that include the cartridges and diagnostic instruments for use with the analytical assay reaction cartridges/kits, as well as methods of making and using the cartridges/kits.

A biological sample storage container includes a biological sample storage tube and a biological sample storage tube cap. The tube cap is a cap that is to be attached to the tube having a lower closed portion and an upper opening portion, and is for closing the upper opening portion. The tube cap includes a main body portion that enters the upper opening portion of the biological sample storage tube and closes the upper opening portion, an elongated biological sample adhering portion that extends downward from a lower face of the main body portion, and a flange that protrudes laterally outward from the main body portion. The biological sample adhering portion is cuttable and falls into the biological sample storage tube after being cut.

Systems, methods, and devices for analyzing small volumes of fluidic samples, as a non-limiting example, less than twenty microliters are provided. The devices are configured to make a first sample reading, for example, measure an energy property of the fluid sample, for example, osmolality, make a second sample reading, for example, detecting the presence or concentration of one or more analytes in the fluid sample, or make both the first sample reading and the second sample reading, for example, measuring the energy property of the fluid sample as well as detecting the presence or concentration of one or more analytes in the fluid sample.

A multi-channel bio-separation system configured to utilize a cartridge that has a individual, separate integrated reagent (i.e., a separation buffer) reservoir dedicated for each separation channel. The multiple channels may have different characteristics, such as different separation medium of different chemistries, different separation length, different channel sizes and internal coatings. In one embodiment, the cartridge does not include integrated detection optics. Not all channels need to be operative. One or more of the channels in the cartridge may be “dummy channels” that are not operative (e.g., not provided with a capillary tube). A capillary tube may be routed between the reservoir/electrode (anode) of one channel to an electrode (cathode) in another channel, thus allowing a longer length of capillary tube to be used to define a longer separation channel to improve resolution.

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.
