The present invention provides a system and a method for enhancing mass transfer of a gas between a gaseous medium and a liquid medium in reactions involving such a mass transfer, and for effective mixing of the liquid medium.

The present invention provides a system and a method for generating nanobubbles in a liquid medium, which involves one or more movable members, each having a surface and configured to periodically expose at least a portion of the surface to the gaseous medium and the liquid medium to form a wetted surface, thereby generating a renewing wetted surface for enhancing mass transfer of the gas between the liquid medium and gaseous medium; and means for generating an electric field in the proximity of the renewing wetted surface for the generation of nanobubbles without electrolysis of the liquid medium.

The present disclosure relates to blood sample preparation devices and methods. In some embodiments, a method for preparing a blood sample comprises: receiving at a sample preparation machine a sample container containing the blood sample; scanning an identifier of the sample container, the identifier containing information indicative of a characteristic of at least one of the sample container or the blood sample contained therein, actuating, after the scanning, and based on the information, the sample container to repeatedly change a position of the sample container; determining, based on the information, whether the sample container should be centrifuged; and transporting the sample container to a centrifuge to be centrifuged and then to a storage compartment when the determining indicates that the sample container should be centrifuged, and to the storage compartment without entering the centrifuge when the determining indicates that the sample container should not be centrifuged.

A method of bulk handling includes providing a sealed and partially full bulk container; suspending the bulk container within a frame; and rotating the frame about an axis in order to rotate the bulk container through multiple revolutions of 360 degrees. During rotation of the frame, an uppermost end of the frame or bulk container becomes lowermost after a first 180 degrees of rotation and is returned to an uppermost position after a further 180 degrees of rotation.

An apparatus is provided which comprises a barrel having a substantially cylindrical configuration. The barrel comprises an exterior surface and defines an interior volume. A base unit comprises a drive motor being configured to rotate the barrel by interfacing with the exterior surface of the barrel. The barrel comprises a thermoelectric heat pump attached thereto and being controllable for at least one of transferring heat out of the interior volume and transferring heat into the interior volume.

Provided is a centrifuge that preferably performs processes such as dispersion of a material to be processed while enhancing convenience for users. A centrifuge 1 of the present invention includes an ultrasonic wave generation source 10 that generates ultrasonic waves and a storage container 20 that stores a material to be processed M. The centrifuge 1 of the present invention also includes a rotation mechanism 30. The rotation mechanism 30 rotates the storage container 20 around a rotation axis L tilted relative to a virtual line V extended in a vertical direction in such a manner that the ultrasonic waves from the ultrasonic wave generation source 10 are constantly applicable to the material to be processed M.

A drug container is arranged in a horizontal state where a central axis extends along a horizontal direction, and the drug container is rotated about the central axis. In such a way, a drug solution in the drug container is moved along an inner surface of the drug container, and the drug container is reciprocally vibrated along the central axis in a state where the drug container is rotated, to stir the drug solution.
