Provided in one implementation is a method that includes introducing a volume of raw material into a chamber of a cavitation machine. The raw material can include a mixture comprising a powder and a solvent. The powder can have a first average particle size in the raw material. The method includes applying a hydrodynamic cavitation process to the raw material to produce a product material. The powder can have a second average particle size, smaller than the first average particle size, in the product material. The method includes causing the product material to exit the cavitation chamber and drying the product material to remove the solvent. Apparatus employed to apply the method are also provided.

In some aspects, the present disclosure pertains to systems for forming hydrogel compositions, the systems comprising a first reservoir containing an iodinated polymer composition that comprise an iodinated polymer having multiple cyclic imide ester groups, a second reservoir containing a buffered diluent solution having a first pH that comprises water, a first buffering agent and a polyamine compound, and a third reservoir containing a buffered accelerant solution having a second pH that is higher than the first pH and comprises water and a second buffering agent. Other aspects of the present disclosure pertain to methods of using such systems for forming hydrogel compositions.

Embodiments include a system for generating nanobubbles in a solvent, including a device for generating a reverse and forward flow in the solvent, wherein the solvent has one or more gases dissolved in it; and a Tesla valve fluidly coupled to the device, wherein the device pushes the solvent through the Tesla valve one or more times alternatingly in a forward and reverse direction to generate nanobubbles of a desired concentration and size. Aspects include a method for generating nanobubbles in a solvent, including filling a device with a desired solvent containing one or more gases dissolved in it; wherein the device is capable of generating a reverse and forward flow in the solvent, and wherein a Tesla valve is fluidly coupled to the device; and using the device to push the solvent through the Tesla valve one or more times alternatingly in forward and reverse directions to generate nanobubbles.

An analysis instrument may perform analytical operations on an analyte that is combined with multiple reagents prior to being introduced into a flow cell. The instrument may include a nozzle sipper that aspirates reagents from a recipient, along with an analyte. The reagents may be directed to a volume and may be repeatedly moved into and out of the volume by cycling of a pump. The reagents may be ejected into a destination recipient with the nozzle sipper promoting vorticity in the recipient to enhance mixing. The repeated aspiration and ejection through the nozzle sipper effectively mixes the reagents and the template in an automated or semi-automated fashion.

A method using a chemical analyzer for removing a component of a liquid sample which may interfere with a test performed on a test assay includes the steps of adding the liquid sample to a sample cup, transferring a volume of the liquid sample to a mixing cup containing an IMAC (Immobilized Metal Affinity Chromatography) resin containing porous beads to form a sample/resin solution in the mixing cup, using a pipette of the chemical analyzer to repeatedly aspirate the sample/resin solution into a disposable pipette tip of the pipette and expelling the sample/resin solution from the pipette tip into the mixing cup to achieve a mixed sample/resin solution in the mixing cup, and allowing the mixed sample/resin solution in the mixing cup to rest undisturbed so that the interfering component of the liquid sample adheres to the porous beads and the beads settle to a bottom portion of the mixing cup, resulting in a refined liquid sample devoid of the interfering component and occupying an upper portion of the mixing cup for later dispensing on the test assay.

A tattoo ink mixing apparatus has a housing having a cavity, a plunger movable between a first position and a second position, and a dynamic member disposed in the cavity and adapted to engage with the plunger distal end. The dynamic member moves in response to movement of the plunger and alternatively creates a suction force and an expulsion force in the opening of the distal end of the housing as the plunger moves between its first and second positions.

A liquid storage apparatus including: a stirring portion including a storage unit configured to store liquid and a drive unit configured to drive the storage unit; and a storage portion configured to store the stirring portion, the storage portion being opened and closed by an opening and closing member, wherein in a case where a stop condition relating to a state of the opening and closing member is satisfied, rotation of the storage unit by the drive unit is stopped.

A liquid agitating apparatus includes a first storing container configured to store a first liquid, a first agitating mechanism configured to agitate the first liquid in the first storing container by causing the first storing container to undergo a first movement, a second storing container configured to store a second liquid different from the first liquid; and a second agitating mechanism configured to agitate the second liquid in the second storing container by causing the second storing container to undergo a second movement different from the first movement.

A liquid stirring apparatus comprises storage means for storing a liquid; and driving means for performing a rotation operation of rotating the storage unit. The rotation operation includes a stop operation of stopping rotation of the storage means at a plurality of stop positions. The plurality of stop positions include a first stop position at which a stop time is a first time, and a second stop position at which the stop time is a second time different from the first time.
