A system for mixing a sample with a combined buffer includes a sampler body, the sampler body including a first reservoir and a second reservoir. The system further includes a first separator forming a first enclosure with the sampler body for the first reservoir. The system further includes a second separator forming a second enclosure with the sampler body for the first reservoir. The system further includes a third separator, in conjunction with the second separator, forming a third enclosure and a fourth enclosure, respectively, both in conjunction with the sampler body, for the second reservoir.

Shaker comprising a frame, a tray for receiving one or more samples and a drive for the tray, in which a tray shaft is mounted eccentrically in a drivable hollow shaft. The tray shaft is fixedly connected to the tray and secured against rotation relative to the frame.

The present technology discloses a cost-effective, single use bag or container for storing biological substances that incorporates on its inner wall an electronic device that is configured to measure physiological and/or physical parameters of the enclosed biological substances, such as source history, identification, demographics, time stamping, temperature, pH, conductivity, glucose, O.sub.2, CO.sub.2 levels etc. The electronic device of the disclosed bag comprises a sensor configured to measure physiological and/or physical parameters of the biological substances enclosed within the bag, and a radio-frequency (RF) device communicably coupled to the sensor and configured to: (a) acquire from the sensor data associated with the measured parameters, (b) store the acquired sensor data in nonvolatile memory, and (c) communicate the stored data wirelessly to a RF reader.

A microscope slide holder comprising a slide support member and at least one acoustic source for introducing acoustic waves to a microscope slide in communication with the slide support member such that one or more fluids present on the surface of the microscope slide are contactlessly mixed.

Example implementations relate to print substance container vibration. A vibrator for a print system may comprise a motor, and a vibration shaft coupled to the motor to cause vibration to provide redistribution of print substance of a print substance container. The vibration may be caused in response to the rotation of an eccentrically loaded weight about a central axis of the vibrator.

Provided herein are methods and devices for identifying and/or distinguishing UCA formulations and specifically activating such formulations to produce UCA suitable for in vivo use.

A storage system is provided. The system may include a tray having at least one recess in which at least one syringe is disposed, the syringe including a barrel with first and second barrel ends, and a stopper fixedly disposed between the first and second barrel ends. A tool attached to the stopper through the second barrel end, the tool having a first end attached to the stopper and a second end attached to or abutting the barrel or a surface of the recess, the first end being selectively adjustable relative to the second end to vary the distance between the first and second ends of the tool. In addition or in the alternative to the tool, the system may include a motion generator attached externally to the syringe, the motion generator being one of at least a vibration generator and a rotating frame.

A container, that includes a transparent portion, which reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component is placed into the interior portion. A second liquid component is poured into the interior portion. The lid of the container is closed to fully enclose the first and second liquid components. The components are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid is opened to expose the mixture of uniform color. The mixture of uniform color is poured from the container into a receiving structure. The mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.

An ultrasonic mixing reactor configured for mixing of plant nutrients for greater absorption using cavitation. The reactor includes a venturi nozzle fluidly connected to a nozzle device having at least one annular shaped plate comprised of a plurality of apertures constructed and arranged to create cavitation. The nozzle device is fluidly coupled to a first ultrasonic reactor having a plurality of variable frequency ultrasonic transducers mounted within the first ultrasonic reactor for generating acoustic cavitation of the bulk mixed plant nutrients. The first ultrasonic transducer is fluidly connected to a second ultrasonic reactor having a plurality of variable frequency ultrasonic transducers mounted within the second ultrasonic reactor for generating acoustic cavitation of the bulk mixed plant nutrients. The second ultrasonic reactor discharge is fluidly coupled to a plate static mixer constructed and arranged to create hydrodynamic mixing.
