A tinting system includes a storage system and a colorant dispenser. The storage system includes a container that defines a fluid-tight, sealed chamber within which a colorant containing reduced levels of biocide (fungicide and/or bactericide) is stored. A valve is positioned at and sealed to an opening provided in the container. The colorant dispenser includes an inlet configured to be releasably and removably attached to the valve of the container. A pump and dosing valve of the colorant dispenser are operated to dispense colorant from the storage system through a discharge nozzle of the colorant dispenser. The dispensed colorant may be used to tint an aqueous-based paint.

The present technology provides a technology that liquid in round-bottom vessels is efficiently agitated. There is provided a vessel rack at least including a holder having a plurality of through-holes into which round-bottom vessels each having a closed-bottom tube shape are inserted, and a support having a plurality of supporting holes that are arranged facing to the through-holes and support bottoms of the round-bottom vessels, the bottoms of the supporting holes each having a bulge such that liquid in the round-bottom vessels forms a vortex at a time of agitation of the liquid. Also, there is provided an agitator of agitating liquid in round-bottom vessels at least including the vessel rack, a mounting unit that mounts the vessel rack, and a rocking unit that rocks the mounting unit, and the like.

Disclosed herein are a sonic homogenizing module (100, 200, 300) and a biological sample preparation system (500) containing the same. The sonic homogenizing module (100, 200, 300) comprises a rod made of a magnetic material (120, 220, 320); a piezoelectric conductor (130, 230,330); a driver (140, 340); and a sleeve-coupling member (110, 210, 310) having a first portion defining a space (112, 212, 312) for coupling with a gripper module of a biological sample preparation system, and for accommodating the piezoelectric conductor and the driver therein; and a second portion having a conduit (114, 214, 314) for receiving the rod therethrough; wherein the driver (140, 340) is electrically coupled with the piezoelectric conductor (130, 230,330) and is configured to drive the piezoelectric conductor (130, 230, 330) to generate a sonic vibration at a frequency of 100 KHz-1 MHz.

Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.
