A system for preparing solutions for chromatography application is disclosed. The system comprises a T-joint for preparing a buffer solution by mixing at least one first solution and a second solution. The T-joint receives the second solution from a solution supply unit connected to the T-joint. Further one or more low pressure pumps supply the one or more first solutions into the T-joint. The high pressure pump collects the buffer solution and delivers it to a chromatography apparatus.

Shown and described is a device (100) for dosing and/or preparing a mixture of substances, in particular a medium or a buffer, the device (100) comprising: at least one first container (102), which is designed to receive at least one solid component, at least one first dosing device (104) for dosing the at least one solid component, the first dosing device (104) being connected to or can be connected to the first container (102), at least one fluid connection (110, 110′) to connect to at least one second container (103, 103′), which is designed to receive at least one fluid, and/or a fluid line for supplying a fluid, and at least one second dosing device (108, 108′) for dosing the at least one fluid, the second dosing device (108, 108′) being connected or connectable to the second container (103, 103′) or to the fluid line, respectively. the fluid line, wherein the at least one second container (103, 103′) and/or the at least one second dosing device (108, 108′) are replaceable and are developed as disposable articles, and/or wherein the at least one first container (102) and/or the at least one first dosing device (104) are replaceable and are developed as disposable articles.

A medicament preparation system includes a disposable cartridge with a flow path. Various sensors may be placed on the cartridge to measure qualities of the fluid flowing through the flow path. The sensors are placed in precise locations using various approaches that make manufacturing of the cartridge efficient and repeatable. A drain line that is susceptible to fouling may be preattached and various approaches are used to remove or reduce the fouling. An elastomeric contact can also be present in the medical preparation system and used in a conductivity measurement subsystem.

A dispenser includes a dock configured to be fixed in place at a use device and a solid product holder configured to be removably secured to the dock. The dock has a first portion including a fixation element that is configured to fix the dock in place at the use device and a second portion including a receiving structure. The solid product holder includes a retaining structure, a base, and a support structure. The retaining structure is configured to removably secure the solid product holder to the receiving structure at the second portion of the dock. The base defines a plurality of apertures that form an open area at which the liquid is received at the solid product holder. The support structure extends from the base and defines an internal volume for holding the solid product at the solid product holder.

A system for mixing a batch of medicament has a pump actuator, control valve actuators, a source of concentrate, and a purified water source, all connected by a fluid circuit. A controller controls various control valves to open fluid channels from the source of concentrate and from the purified water source to connect a junction of the fluid circuit to the concentrate container and the purified water source. The controller also controls the pump actuator and a water pump to flow water and concentrate through the junction into a mixing container, such that the mixture of the concentrate and the water requires additional dilution to form a ready-to-use medicament. The controller samples the mixture and calculate an additional quantity of water to add based on the sampling.

A method of producing paint includes: measuring an impedance of paint containing a magnetic powder; and controlling stirring of the paint on the basis of the measured impedance.

Disclosed herein is a device and method for changing the conditions of a solution flowing in a serial path. In particular, disclosed herein is a device that includes a chemical reactor, a first system, and a second system that are each serial to one another. Each of the first system and the second system include a mixing chamber, a solvent reservoir, a solvent pump, and one or more detectors. Also disclosed herein is a method for changing the condition of a solution that includes flowing a liquid sample in a path, serially mixing the sample with at least two discrete solvents while it flows through the path, and detecting the condition of the sample after it is mixed with each solvent.

A system for mixing a liquid with a powder into a solution batch includes a hopper (20) into which said powder is deposited, the hopper (20) having a powder outlet (22) therein. A mix tank (60) is also provided having a liquid supply inlet (62), a recirculation inlet (64), and a solution outlet (66). A mix pump (40) that is in fluid communication with the solution outlet (66), the powder outlet (22), and the recirculation inlet (64) operates to mix and transfer the solution.

An apparatus for dissolving a gas into a liquid includes a liquid inlet for supplying liquid into the apparatus, a gas inlet for supplying gas into the liquid within the apparatus and a venturi arranged to dissolve the gas into the liquid passing through the venturi. The apparatus also includes an outlet 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 integrally formed in a single piece of material.
