A composite analysis device, configured to perform a plurality of types of analyses, which prevent a shortage of a volume of a specimen. The analysis device can execute a plurality of measurement processing steps for a biological sample based on order information. The analysis device includes: a pierce nozzle unit which pierces a hole in a sealed sample container in which the biological sample is contained, collects the biological sample, and discharges the biological sample into a predetermined containing unit; a sample nozzle unit which dispenses the biological sample contained in the containing unit into one or more cuvettes; and a control device which control operations of the pierce nozzle unit and the sample nozzle unit based on the order information.

An automatic analysis device improves the uniformity of a mixed liquid by noise agitation by a dispensing mechanism. The dispensing mechanism agitates a mixed liquid by suctioning the mixed liquid into a reaction vessel by a nozzle and then re-discharging the suctioned mixed liquid into the reaction vessel. When the mixed liquid is re-discharged into the reaction vessel, the nozzle is moved upward at a speed higher than a speed at which the liquid surface of the mixed liquid rises due to the re-discharging of the mixed liquid from the nozzle during a first period and lowers the speed of moving the nozzle upward than the speed during the first period while maintaining or reducing the speed at which the liquid surface of the mixed liquid rises due to re-discharging of the mixed liquid from the nozzle during a second period following the first period.

The present disclosure provides systems, devices, and methods for distributing reagents between multiple bioprocessing devices. In some cases, a valve apparatus described herein comprises: (a) a first manifold comprising one or more reagent ports configured to receive a reagent; (b) a second manifold comprising one or more fluid channels; and (c) a third manifold comprising (i) one or more input ports configured to direct said reagent to a bioprocessing device or (ii) one or more output ports configured to receive a fluid from said bioprocessing device; wherein said second manifold is disposed between said first manifold and said third manifold along an axis, wherein said first manifold or said second manifold is configured to rotate around said axis from a first closed position to a first open position.

Systems, devices, and methods for dispensing a of fluidic sample to each of a plurality of targets are disclosed. An example apparatus for dispensing a fluidic sample includes an inlet port to input a sample material, and a first sample nozzle and a second sample nozzle fluidically coupled to the inlet port to expel the sample material, wherein a tubular junction fluidically couples the inlet port to a first tubular fluid path that terminates in the first sample nozzle and to a second tubular fluid path that terminates in the second sample nozzle, wherein a cross-sectional area of the tubular junction is less than an average cross-sectional area of the first tubular fluid path and the second tubular fluid path, and wherein the cross-sectional area of the tubular junction is selected to draw the sample material from the inlet port into the tubular junction via capillary action.

An autoclaving microplate washing system for cells and non-adhering three-dimensional (3D) cell cultures includes one or more pumps for controlling the dispensing of washing fluid and the evacuation of fluid from microwells to gently wash the cells. A method of controlling the autoclaving microplate washing system includes controlling the one or more pumps for dispensing and evacuation.
