Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

Disclosed herein are devices, apparatuses, and methods for generating a reciprocating motion for the purpose of grinding or homogenizing samples. An apparatus includes a connecting linkage that extends along a longitudinal axis. The apparatus includes a sample vial holder attached to the connecting linkage. The apparatus includes a crank operatively connected to the proximal end of the connecting linkage, the crank configured to impart rotational motion to the proximal end of the connecting linkage. The apparatus includes a sliding carriage operatively connected to the distal end of the connecting linkage, the sliding carriage configured to restrict the distal end of the connecting linkage to a linear path. The apparatus includes a motor operatively connected to the crank to rotate the crank such that the sample vial holder, in use, moves with a combination of rotational and linear motion.

A two-component paint system (1) comprises a medium pressure canister (10) with a paint, at least one solvent and at least one propellant, and a high pressure canister (20) with a hardener, at least one solvent, at least one propellant and an inert gas or inert gas mixture. An adapter (30) is configured to transfer the content of the high pressure canister (20) into the content of the medium pressure canister (10). The internal pressure of the high pressure canister (20) is at least 2 bars higher than the internal pressure of the medium pressure canister (10).

A kit and a method for using the kit to generate nanoseeds from protein nanocrystals and aggregates is disclosed. The method comprises mixing a plurality of beads with a protein nanocrystal or aggregate, and agitating the mixture to generate the nanoseeds. Nanoseeds made by disclosed embodiments may be of a high quality, as evaluated by TEM, and can be used to produce high quality protein crystals. Additionally, spectroscopic techniques, such as UV fluorescence and/or brightfield microscopy can be used to identify aggregates suitable to produce nanoseeds.

The disposable assembly has a closed body, for containing a first component and having a lateral surface, a bottom and an upper opening. The bottom has a mounting projection extending within the body for its sealed interlocking engagement in the complementary conformation of the lower end of a hollow inner tubular member intended to contain a second component while its other end is closed by a sealing means. A shutter is tightly mounted on the opening of the body using screws, or by clipping or interlocking. The shutter and the sealing means or the shutter and the hollow tubular element can be a single piece. The presently described embodiments are suitable for producers of paint, varnishes, primers and other products to be sprayed or projected using a gun and other manufacturers of spray or paint guns.

A centrifugal mixing device can include a shaft assembly that is operably coupled to a motor such that the motor rotates the shaft assembly about a first axis. The devices can further include a turret that is rotatably coupled to the shaft assembly such that the turret rotates about the first axis relative to the shaft assembly. The turret can include a first support, a first canister rotatably coupled to the first support such that the first canister rotates about a second axis, and a second canister rotatably coupled to the first support such that the second canister rotates about a third axis. The turret is configured to rotate about the first axis in a first rotational direction and each of the first and second canisters is configured to rotate about the second and third axes, respectively, in a second rotational direction that is opposite the first rotational direction.
