Provided herein are devices, systems, and methods for particle sorting, including cell sorting, using microfluidics cartridges and microchips and the manufacture of the microfluidics cartridges and microchips by high-throughput approaches. Such methods, devices, and systems can be used to identify, sort, and collect a subset of particles or a single particle from a sample. The capability to manufacture such microfluidic tools in high volume may lower production costs and allow for the microfluidic tools to be used as consumables.

A feedstock processing system extracts a product from a solid using a CTSE system comprising a plurality of continuous stirred tank extraction stages arranged in fluid communication with each other in series such that effluent from one stage flows to a next stage in the series. One of the stages has an inlet to allow a measured amount of liquid solvent and the solid to be introduced to the continuous stirred tank extraction stage. The stage mixes the solid with the introduced solvent to form a homogeneous slurry to enable the product associated with the solid to be extracted with the solvent. A solid-liquid separator is arranged in fluid communication with the continuous stirred tank extraction stages, and receives an effluent from one of the stages and separates the liquid solvent containing the product from the solid to form a product-containing liquid and a product-depleted solid.

The object of the invention is to perform, rapidly and at a low cost, a pretreatment of an analysis sample containing a turbid substance. Provided is an analysis sample pretreatment apparatus in which a clarified liquid is obtained by removing a turbid substance from an analysis sample. The analysis sample pretreatment apparatus includes a cell configured to store the analysis sample, and a cell holder in which at least a part of a housing is opened to mount the cell. The cell holder includes an ultrasonic wave transducer and an ultrasonic wave reflection plate that are disposed on facing plane pairs while sandwiching the cell mounted inside the cell holder. The cell includes a first opening unit from which the analysis sample flows in, a second opening unit from which the clarified liquid flows out, and a third opening unit from which the turbid substance is discharged. In a state where the cell is mounted in the cell holder, the first opening unit is provided at a position lower than an upper end of the ultrasonic wave transducer in a vertical direction, or at a position higher than a lower end of the ultrasonic wave transducer in the vertical direction.

A mesh filter for a fuel system of a vehicle may include: a frame for maintaining a shape thereof; a mesh member coupled to the frame so as to remove foreign substances contained in fuel, where the mesh member includes a first mesh member and a second mesh member; and an opening unit for opening and closing a fuel path in the first mesh member. In particular, the second mesh member has a mesh size smaller than a mesh size of the first mesh member such that the mesh filter inhibits clogging of the mesh filter with paraffin wax.

The purpose of the present invention is to collect a plurality of microscopic objects dispersed in a liquid by light irradiation, and also trap them. A collecting device for bacteria collects a plurality of bacteria dispersed in a sample liquid. The collecting device is provided with a laser beam source that emits laser beam and a honeycomb polymer film constituted so as to be able to hold the liquid. Walls prescribing pores for trapping the plurality of bacteria dispersed in the liquid are formed on the honeycomb polymer film, and also a thin film that includes a material for converting light from the laser beam source to heat is formed on the honeycomb polymer film. The thin film heats the liquid of the sample through the conversion of the laser beam from the laser beam source to heat, thereby causing a convection in the liquid.
