A continuous acoustic chemical microreactor system is disclosed. The system includes a continuous process vessel (CPV) and an acoustic agitator coupled to the CPV and configured to agitate the CPV along an oscillation axis. The CPV includes a reactant inlet configured to receive one or more reactants into the CPV, an elongated tube coupled at a first end to the reactant inlet and configured to receive the reactants from the reactant inlet, and a product outlet coupled to a second end of the elongated tube and configured to discharge a product of a chemical reaction among the reactants from the CPV. The acoustic agitator is configured to agitate the CPV along the oscillation axis such that the inner surface of the elongated tube accelerates the one or more reactants in alternating upward and downward directions along the oscillation axis.

Large bioreactors based on microfluidic technology, and methods of manufacturing the same, are provided, The big microbioreactor can include a chip or substrate having the microfluidic channels thereon, and the chip can be manufactured by forming a master mold, forming a male mold from a photopolymer plate using replica molding with the Fmold, and transferring features of the male to a polymer material.

The invention generally relates to assemblies for displacing droplets from a vessel that facilitate the collection and transfer of the droplets while minimizing sample loss. In certain aspects, the assembly includes at least one droplet formation module, in which the module is configured to form droplets surrounded by an immiscible fluid. The assembly also includes at least one chamber including an outlet, in which the chamber is configured to receive droplets and an immiscible fluid, and in which the outlet is configured to receive substantially only droplets. The assembly further includes a channel, configured such that the droplet formation module and the chamber are in fluid communication with each other via the channel. In other aspects, the assembly includes a plurality of hollow members, in which the hollow members are channels and in which the members are configured to interact with a vessel.

A planar flow reactor includes a straight planar process channel, a flow generator, and a plurality of static mixing elements disposed within the process channel. The flow generator is configured to generate a pulsatile flow within the process channel, and the static mixing elements are configured to locally split and recombine the flow. The straight planar process channel enables the generation of a flow pattern that is largely independent of the width of the process channel, meaning that the throughput may be increased by increasing the width without significantly affecting the residence time distribution or the flow behavior. Furthermore, by creating a pulsatile flow within the process channel, turbulence and/or chaotic fluid flows may be generated even at low net flow rates, i.e. low net Reynolds numbers.

Provided is a method for manufacturing a polymer by a flow-type reaction, including introducing a liquid A containing an anionic polymerizable monomer and a non-polar solvent, a liquid B containing an anionic polymerization initiator and a non-polar solvent, a liquid C containing a polar solvent, and a polymerization terminator into different flow paths; allowing the liquids to flow in the respective flow paths; allowing the liquid A and the liquid B to join together at a joining portion; allowing a conjoined liquid M.sup.AB of the liquid A and the liquid B to join with the liquid C at downstream of the joining portion; subjecting the anionic polymerizable monomer to anionic polymerization while a conjoined liquid M.sup.ABC of the conjoined liquid M.sup.AB and the liquid C is flowing to downstream in a reaction flow path; and allowing a polymerization reaction solution flowing in the reaction flow path to join with the polymerization terminator so that the polymerization reaction is terminated and a polymer is obtained, in which a polarity of a solvent of the liquid M.sup.ABC is made higher than a polarity of a solvent of the liquid M.sup.AB. Also provided is a flow-type reaction system suited for performing the manufacturing method.
