A photometric dispensing nozzle unit, a photometric dispensing apparatus, and a photometric dispensing method are for preventing an increase in apparatus scale and have a simple structure to be easily handled. A nozzle performs suction/discharge of gas through a distal end opening and can have a dispensing tip attached thereto. A light guide end portion is provided in the nozzle and can receive or irradiate light at a distal end of the nozzle. A dispensing cylinder has a cylinder having a cavity therein, a plunger that is slidable in the cavity, and a suction/discharge port that performs suction/discharge of gas. A suction/discharge flow path passes through the nozzle and communicates with the suction/discharge port and the distal end opening of the nozzle. A light guide path is optically connected to the light guide end portion through the nozzle but not through the dispensing cylinder.

Instrument for performing a diagnostic test on a fluidic cartridge A cartridge reader is for carrying out a diagnostic test on a sample contained in a fluidic cartridge inserted into the reader. The fluidic cartridge comprises a fluidic layer comprising at least one sample processing region, at least one collapsible blister containing a liquid reagent, a pneumatic interface, an electrical interface and at least one mechanical valve. The reader comprises a housing; an upper clamp occupying a fixed position relative to the reader, and a lower clamp, movable relative to the first clamp, wherein the upper clamp and the lower clamp define a cartridge receiving region therebetween. The reader comprises a thermal module comprised in the lower clamp, wherein the thermal module comprises at least one thermal stack for heating the at least one sample processing region of the cartridge inserted into the reader. The reader comprises at least one mechanical actuator for actuating the mechanical valve comprised in the cartridge inserted into the reader.

One or more liquids are transferred from a source array to one or more remotely positioned destination sites such as chambers by utilizing one or more movable transfer elements, such as contact pins or capillaries. The source array may include a predetermined organization of addresses at which materials are positioned. One or more materials may be selected for transfer. Based on the selection, one or more addresses may be accessed by the transfer element(s). The addresses may correspond to spots on a surface of the source array. Each spot may be a feature containing one or more (bio)chemical compounds. At the chamber(s), the material(s) may be processed, such by reaction with one or more reagents. The reaction(s) may entail synthesis of one or more desired products. Alternatively, reaction(s) may be performed at the source array, and the product(s) then transferred to the chamber(s).

A cartridge reader is configured to carry out a diagnostic test on a fluid sample contained within a fluidic cartridge. The cartridge comprises first, second and third collapsible blisters containing at least one reagent for use in the diagnostic test. The cartridge reader comprises an upper clamp, occupying a fixed position relative to the reader and a lower clamp, movable relative to the upper clamp, and wherein the upper clamp and the lower clamp are configured to receive and hold a fluidic cartridge therebetween. First, second and third blister actuators are mounted on the upper clamp, for aligning with first, second and third collapsible blisters of a fluidic cartridge inserted into the reader. The first, second and third blister actuators are movable relative to the upper clamp, between a first position in which the blister actuators are spaced apart from the collapsible blisters comprised on the fluidic cartridge received between the upper and lower clamps, and a second position in which the blister actuators depress the collapsible blisters, thereby collapsing the blisters and ejecting the reagents contained therein into a channel in the microfluidic cartridge.

A matrix droplet extruder includes a casing; one or a plurality of reagent containers; a plurality of pneumatic connectors on the casing that are each configured to be connected to a pneumatic actuator to provide controlled pneumatic pressure to one or more of said plurality of the pneumatic connectors; a droplet matrix extrusion surface with one or a plurality of printing zones, each printing zone comprising an array of perforations; and a liquid management chip for dispensing one or more reagents from said one or a plurality of reagent containers through the array of perforations of said one or a plurality of printing zones, so as to repeatedly generate a matrix of droplets when applying the pneumatic pressure to said one or more reagents.
