Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

An inline buffer dilution system is provided that includes a first flow control valve fluidly connected to a supply of diluent liquid, second and third flow control valves fluidly connected to supplies of a first buffer and a second buffer, respectively, and a mixing pump fluidly connected to the first, second, and third flow control valves and configured to mix an amount of the diluent liquid, the first buffer, and the second buffer to produce a diluted buffer solution. The system further includes a backpressure control valve configured to generate a backpressure that promotes mixing within the mixing pump, and a controller configured to control the backpressure based on the amount of the diluent liquid, the first buffer, and the second buffer being mixed in the mixing pump, such that the mixing pump yields a minimum mixing threshold across a range of fluid flows.

A sensor system, particularly for monitoring the mixing of at least two fluids and a method for monitoring the mixture of at least two liquids. The present invention provides a sensor system for fluids, comprising at least two level sensor which are arranged vertically one upon the other on and connected to an electronic circuit board, four electrodes of four conductivity sensors which are arranged horizontally next to each other at the bottom of and connected to the electronic circuit board; and a temperature sensor which is connected to the electronic circuit board; a connector for connecting the electronic circuit board to a controller; wherein the electronic circuit board is embedded in a hot melt compound which is surrounded by an injection molded housing.

An apparatus (2) for dissolving a gas into a liquid includes a liquid inlet (4) for supplying liquid into the apparatus, a gas inlet (6) for supplying gas into the liquid within the apparatus and a venturi (52) arranged to dissolve the gas into the liquid passing through the venturi. The apparatus also includes an outlet (18) for the liquid and dissolved gas downstream of the venturi. At least part of the liquid inlet, at least part of the gas inlet, at least part of the venturi and at least part of the outlet are formed in an integrally formed piece of material (42).

Methods and systems for chromatography are disclosed that employ a flexible container configured to fit within a support structure and adapted to receive a filtration or absorptive medium. The flexible container can include at least one inlet, at least one outlet, and a separation barrier peripherally sealed within the container to separate the container into a resin containing portion and a drainage portion. The barrier can be configured to exclude the resin material from the drainage portion while allowing fluids to pass therethrough. The disposable chromatography system can further include one or more agitators disposed within the flexible container and adjustably configured to be raised or lowered in the flexible container. When the agitator is in the raised position, the resin packing material can operate in a settled, packed-bed configuration. Alternatively, the agitator in the lowered position permits the chromatography resin packing material to operate in a mixed, slurry configuration.

Embodiments of a process for treating a fluid are provided. The process for treating a fluid includes supplying a first fluid to a circulating chamber and introducing a first gas to the first fluid. A portion of the first gas is dissolved in the first fluid and a portion of the first gas is held in a head space portion of the circulating chamber. The process further includes mixing a portion of the first fluid drawn out from the circulating chamber and a portion of the first gas drawn out from the head space portion to form a mixture. The process further includes spraying the mixture back into the circulating chamber by a two-fluid nozzle. In addition, the first gas is further dissolved into the first fluid to form a high conductivity fluid. The process further includes draining the high conductivity fluid from the circulating chamber.

An apparatus and method for manufacturing an electricity storage material are provided which allow easily measuring the dissolution rate to solubility of a solution of a powder thickener dissolved in a liquid solvent. An apparatus for manufacturing an electricity storage material includes: a dissolving device that dissolves in a liquid solvent a thickener as powder that is ionized when dissolved; and a dissolution-rate-to-solubility determining device that measures conductivity of the solution produced by the dissolving device and determines a dissolution rate to solubility of the solution based on the measured conductivity. The dissolution rate to solubility can thus be determined without the need to stop the dissolving device during dissolution of the thickener in the liquid solvent. This can significantly improve production efficiency. Since excessive operation of the dissolving device can be prevented, energy saving can be achieved.
