An apparatus for preparing a reagent solution includes an enclosure and a container disposed within the enclosure. The container defines an internal cavity having a compressible volume and defines a passage providing fluidic communication between the internal cavity and the exterior of the container. Optionally, a compressible member is disposed within the internal cavity. A reagent is disposed within the internal cavity.

A method of processing products in a retort having a length includes arranging products in at least one product carrier for movement along at least a portion of the length of the retort and reciprocating the at least one product carrier along at least a portion of the length of retort in a non-sinusoidal pattern of movement.

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.

The disclosure is directed to a sample preparation apparatus for grinding or homogenizing test samples. More specifically, the disclosure relates to grinding samples using rotational and linear motion. Grinding samples can be accomplished with an apparatus with a slider-crank mechanism that is attached to an oscillating connecting linkage. The amplitude of oscillatory motion can be greater than or equal to a length of a sample processing chamber.

The present invention relates to a shaking platform for a laboratory shaking device having an adjustable holding device for fastening at least one container, the shaking platform having a length and a width, and the holding device comprising: a base plate having a fastening device for fastening the holding device on the shaking platform, at least two supports that protrude from the base plate and that form a container-receiving space arranged between the supports, and at least two holding rods carried by the supports and running substantially parallel to the shaking platform, which holding rods delimit the container-receiving space and whose distance from one another can be adjusted via an adjusting rail, the length and the width being greater than a length of the holding rods. The present invention also relates to an adjustable holding device and a laboratory shaking device.

A machine (10) to automatically prepare a fluid coloring product inside a container (15), which can already contain a base product, comprises a loading station (26), a perforating device to make an aperture in the upper part of the container (15), a delivery device (21) configured to deliver coloring substances inside the container through such aperture, and a closing device configured to automatically closed such aperture with a closing element, after the delivery of the coloring substances.

A mixing apparatus includes a housing that includes a first end wall, a second end wall, and a top wall that at least partially define a cavity of the housing. The apparatus also includes a pair of rollers extending from the first end wall to the second end wall and coupled to the housing such that each roller is rotatable relative to the housing. The apparatus also includes a motor positioned in the cavity and enclosed within the housing, the motor operatively coupled to a first roller of the pair of rollers and configured to drive the first roller to rotate for rotating the container. The motor is operatively coupleable to a power source to drive the first roller of the pair of rollers.

Apparatus and method for forming beverages using a beverage cartridge and sonic energy. A cartridge may include a sonic receiver, such as a feature that extends into an interior space of the cartridge and is arranged to receive a sonic emitter that introduces sonic energy into the interior space. The sonic receiver may be excited by sonic energy, which causes the sonic receiver to itself introduce sonic energy into the cartridge.

Analyzers are described that control sample agitation by detecting vibration acceleration and using feedback to control the agitation and also alert to the presence of abnormal agitation. An embodiment provides an analyzer comprising a liquid agitation unit; an agitated liquid analysis unit; and a unit that controls the agitation unit. The agitation unit includes a vibrator of a liquid container and a detector of vibration of the container and that outputs a signal to the control unit, which responds by regulating the vibrator.
