A piezo shaker for shaking a probe is disclosed. The piezo shaker comprises a platform operatively connected with at least one piezo element, wherein the at least one piezo element deforms for controlled movement of the platform, wherein the piezo shaker further comprises transmission means connecting the at least one piezo element and the platform, and wherein the transmission means transmit the movement to the platform. The piezo shaker may comprise two piezo elements, arranged to operate along different directions, in particular perpendicularly.

A method for automatic speed control of an orbital shaker device to determine one of at least two stacked orbital shaker devices operating in an out of balance condition includes the steps of a) Starting the first orbital shaker device, b) Accelerating the first orbital shaker device, and c) Determining a vibration level of the first orbital shaker device, and d) Automatically decreasing a speed of the first orbital shaker device if the vibration level determined in step c) exceeds a predefined first threshold, wherein the steps a) to d) are additionally executed for a second orbital shaker device independently from the first orbital shaker device.

A biological production system includes a mixing vessel and an agitation device. The mixing vessel includes an outer housing, an internal mixing structure, and a reaction chamber. The mixing vessel is configured to provide low shear agitation to materials in the reaction chamber in response to force from the agitation device.

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.
