A fluidic device for capturing or detecting a sample substance contained in a solution includes at least two continuous circulation flow channels selected from the group consisting of: a first type continuous circulation flow channel which is formed of a first circulation flow channel and a second circulation flow channel and which is configured to circulate the solution in the first circulation flow channel and then circulate the solution in the second circulation flow channel; and a second type continuous circulation flow channel which is formed of a third circulation flow channel and a fourth circulation flow channel and which is configured to circulate the solution in the third circulation flow channel and then circulate and mix the solution in both of the third and fourth circulation flow channels, wherein any one of the circulation flow channels has a capturing section which captures the sample substance, and/or a detecting section which detects the sample substance.

An apparatus for preparing a reagent solution includes an enclosure and a container disposed within the enclosure. The container defines an internal cavity having a compressible volume and defines a passage providing fluidic communication between the internal cavity and the exterior of the container. Optionally, a compressible member is disposed within the internal cavity. A reagent is disposed within the internal cavity.

Device for the mixing of polymethylmethacrylate bone cement and for storing a monomer liquid and a cement powder as starting components of the bone cement, comprising a cartridge having an internal space closed on one side by a mobile dispensing plunger; a monomer container for a monomer liquid and/or a connector for attachment of a monomer container which can be opened in the device so that the monomer liquid flows from the monomer container into the device; and a connecting conduit through which the monomer liquid can be guided into the internal space of the cartridge; having a pumping plunger that can be shifted axially in the hollow cylinder arranged in the hollow cylinder, which can be used to push monomer liquid from the hollow cylinder through the connecting conduit into the internal space of the cartridge by actuating the pumping plunger.

A meshing-type rubber internal mixer and a working method thereof are provided. The meshing rubber internal mixer includes a frame mechanism, a mixing mechanism, and an unloading mechanism. The mixing mechanism is on the upper side of the unloading mechanism. The mixing mechanism and the unloading mechanism are in the frame mechanism. An internal mixing chamber is of a closed structure through first automatic telescopic plates and second automatic telescopic plates. The gap between a first meshing-type rotor and a second meshing-type rotor is small, a material is compressed to enter the space between the first meshing-type rotor and the second meshing-type rotor to be extruded with an internal mixing chamber wall. The material is flaky in the internal mixing chamber, so that the material produces great strain deformation, thereby achieving excellent dispersing and mixing effects.

A polymer dispersion system for use in a hydraulic fracturing operation is disclosed. The system comprises (a) a tank assembly comprising an ingress, an egress, and an interior volume for collecting mother solution; (b) a first transfer pump coupled with the egress of the tank assembly: and (c) a second transfer pump coupled with the egress of the tank assembly. The first transfer pump is configured for coupling to a missile unit and a blender unit downstream thereof, but in fluid communication with only one of such units at any given time when coupled. A method of operating said polymer dispersion system is also disclosed.

A system for generating and dispensing plural component materials includes a controller operatively connected to dispense valves and return valves. The return valves are in respective open states to allow constituent materials to circulate back to a source and are in respective closed states to block circulation. The dispense valves are in respective open states to allow mixing of the constituent materials to form the plural component material and in respective closed states to prevent generation and dispense. The controller implements a delay between closing the return valves and opening the dispense valves to build pressure in the system prior to generating and dispensing the plural component material.

An apparatus for preparing a reagent solution includes an enclosure and a container disposed within the enclosure. The container defines an internal cavity having a compressible volume and defines a passage providing fluidic communication between the internal cavity and the exterior of the container. Optionally, a compressible member is disposed within the internal cavity. A reagent is disposed within the internal cavity.

A production module for producing solid medicaments in individual batches, comprising a supplying device for supplying powdered starting materials, a mixing device connected to the feeding device and is intended for working the supplied powdered starting materials into a product, a final working device connected to the mixing device and is intended for the final production of an end product from the worked starting materials, and a control device for automatically controlling the supplying device and the mixing device and the final working device. Diverters allow a batch to be passed on from the supplying device to the mixing device and from the mixing device to the final working device without any backmixing. Data of all the process sensors and quality sensors of the production module are linked with the respective batch by the control device such that tracking and tracing of the batches is made possible.

The invention relates to a mixing device for mixing one or more cosmetic preparations in a dispenser with a dispensing opening (8). The mixing device comprises at least two mixing plates (1) which comprise one or more passages (2), the diameter thereof tapering in direction of the dispensing opening.

One embodiment relates to a device for the production of a bone cement dough from a monomer liquid and a cement powder comprising a cartridge with an internal space; a cartridge head with a dispensing opening; a conveying plunger that is arranged in the internal space of the cartridge and is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a dispensing plunger between the dispensing opening and the conveying plunger that is supported in the internal space of the cartridge such that it is pushable in the direction of the dispensing opening; a first hollow space, in which the cement powder is arranged; a second hollow space that is bordered by the dispensing plunger and the conveying plunger; a fluid opening that is arranged in the conveying plunger; a feedthrough that connects the first hollow space and the second hollow space to each other, and a closure means that is arranged on a rear side of the dispensing plunger. The closure means projects away from the dispensing plunger and is situated at a distance from the fluid opening. The fluid opening is closable with the closure means. The closure means is mobile in the closed fluid opening such that the fluid opening stays closed, while the conveying plunger is pushable further in the direction of the dispensing plunger.
