Abstract: In some examples, a vessel mounting system may include a first collar including at least one flexible member engageable with a groove of a vessel to align the first collar relative to the vessel. A second collar may include at least one clip engageable with a complementary clip of the first collar to engage the second collar with the first collar.

Abstract: In some examples, a vessel mounting system may include a first collar and a second collar. The second collar may include a clip engageable with an edge of the first collar to engage the second collar with the first collar.

Abstract: In some examples, a vessel mounting system may include a first collar including at least one protrusion engageable with a groove of a vessel to align the first collar relative to the vessel. A second collar may include at least one stud disposable in a corresponding aperture of the first collar to align the second collar relative to the first collar.

Abstract: In some examples, a vessel mounting system may include a first collar and a second collar. The second collar may include at least one positioning member to position the second collar relative to the first collar. Further, the second collar may include at least one interlocking member to lock the second collar to the first collar.

Abstract: In some examples, an instrument closure may include an instrument closure retainer to retain the instrument closure onto a container. The instrument closure may further include a sensor retainer including a plurality of apertures for transfer or removal of material, respectively, into or from the container. The sensor retainer may further include a sensor mount to retain a sensor.

Abstract: In some examples, a shaft coupling system may include a first shaft including a disc that is engageable by a second shaft to retain the second shaft with the first shaft when the second shaft is rotated in a first direction, and release the second shaft from the first shaft when the second shaft is rotated in a second direction that is opposite to the first direction. A spring may be mounted to the first shaft to bias the second shaft towards the first shaft when the second shaft is retained with the first shaft. Further, a shaft coupling method may include engaging a second shaft with a disc of a first shaft by rotating the second shaft in a first direction relative to the first shaft, and disengaging the second shaft from the first shaft by rotating the second shaft in a second direction relative to the first shaft.
