Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

An automated transfer and mixing device receives an injection device, a lyophilized drug vial and a diluent vial and transfers diluent from the diluent vial to the lyophilized drug vial and shakes or vibrates the lyophilized drug vial to reconstitute the drug. The device then transfers the reconstituted drug from the lyophilized drug vial to the injection device.

An apparatus comprising: a vessel component comprising a flow-through interior chamber having an interior sidewall and an exterior sidewall; at least two inlets for introducing chemical components into the flow-through interior chamber; at least one outlet for removing product from the flow-through interior chamber; and an off center rotation component which is operatively connected to the vessel component. During operation of the apparatus, the off center rotation component generates vortical movement of at least two chemical components through the flow-through interior chamber of the vessel, and converts at least a portion of the at least two chemical components to at least one reaction product or product mixture. A method of using the apparatus to produce reaction products or product mixtures. The apparatus and method are useful for producing specialty chemicals such as fragrance and flavor compounds, insect pheromones, petrochemicals, pharmaceutical compounds, agrichemical compounds, and the like.

A disposable fluid transfer and mixing device is disclosed and includes an injector support surface for receiving an injection device thereon. A lyophilized drug vial, a diluent vial and a syringe are also attached to the device. The device features fluid passageways and a manual valve that may be manipulated so that the syringe may be used to transfer diluent from the diluent vial to the lyophilized drug vial, for reconstitution of the drug. The valve may also be configured so that the reconstituted drug is transferred from the lyophilized drug vial to the injection device.

A device for shaking samples includes a carrier (62) and a drive element (66) which is rotatably bearing-mounted on the carrier (62) about a drive axle and is drivable by a drive (65). Furthermore, the device includes a tray (61) arranged for loading the samples (69), a tray shaft (67) which is connected to the tray (61) and is bearing-mounted eccentrically on the drive element (66), and a counterweight (66a) which is attached to the drive element (66) and is adapted to compensate for an imbalance occurring during operation of the device with a defined load on the tray (61). A center of gravity of the counterweight (66a) is located opposite the tray shaft (67) in relation to the drive axle of the drive element (66). The center of gravity of the counterweight (66a) and a center of gravity of the tray (61) together with the tray shaft (67) and defined load are located in the same plane orthogonal to the drive axle. When the drive element (66) rotates about the drive axle, a first torque, which is exerted on the drive axle by the tray (61) together with the tray shaft (67) and defined load, is equal in magnitude and directed in the opposite direction to a second torque, which is exerted on the drive axle by the counterweight (66a). As a result, the counterweight (66a) is adapted in such a way that it compensates for both a static and a dynamic imbalance on the drive axle. Accordingly, a shaking frequency of the tray (61) due to the drive (65) reaches at least 1000 rpm, in particular at least 2000 rpm.

A shaker for actuating a fluidic sample in a container, comprising a shaking plate which connected by a first linking rod to a first eccentric drive which is connected to an axis; a counterweight which connected by a second linking rod to a second eccentric drive which if connected to the axis with an offset to the first eccentric drive; and a motor which rotates the axis to which first and second eccentric drive are connected.

A mixing device of FIG. 1B comprises a multi-element spring system in which an eccentric load, coupled to a rotor of a motor, is located towards a first end of a first beam realising a backbone for the mixing device. One or more connections interconnect the backbone respectively to one or more other beams to produce the multi-element spring system. A load, such as a vial or other container in which is located a diluent, is located remotely from the motor. As such, the spring system supports two independent but complementary eccentric load generating subsystems arising from, respectively, the controlled rotation of the rotor [and its eccentric load] and then, in response to rotation of the connected eccentric load on the rotor, swirling of the diluent in the vial/container. Both these eccentric loads contribute to a complex multidirectional flexing of the multi-element spring system [relative to a fixed anchor point].

An agitation apparatus according to one embodiment is an agitation apparatus for use in a container which contains contents and extends in a first direction. The agitation apparatus includes a holder to which the container is attached and a converting member coupled to the holder. The converting member includes an input member which rotates about an axis, and an output member coupled to the holder to output a rotational motion of the input member as a linear motion along the first direction and a direction opposite to the first direction. When the input member rotates about the axis, the container attached to the holder moves linearly together with the output member.
