Vessel for growth of biological entities

A 5-liter bioreactor vessel enables a substantial increase in the volume of biological media that can be cultivated in the vessel compared to conventional designs. Moreover, when agitated at 1.5 the shaking frequency of a conventional 3-liter bioreactor (i.e., 90 rpm versus 60 rpm), the 5-liter vessel achieves a 19% increase in cell aeration without exceeding the maximum shear stress limit for cell viability. The 5-liter vessel optionally includes a plurality of internal baffles configured to disrupt the liquid vortex and reduce the maximum shear stress transferred to biomedia contained within the vessel.

TURNTABLE COLOR MACHINE

The present invention provides a turntable color machine includes a rack, a controller is arranged on the rack, a wheel-type turntable that rotates vertically is arranged on the rack, a plurality of color paste bags are arranged on the wheel-type turntable, the color paste bags are evenly arranged along the circumference of the wheel-type turntable, the color paste bags are connected with a piston pump that is driven by a lifting mechanism to perform constant volume injection via a valve body, and a material receiving device that moves up and down is arranged at the middle of the wheel-type turntable. The piston pump is connected with the color paste bags to achieve volume injection, the wheel-type turntable drives the color paste bags to perform a circular motion, so that the color paste in the color paste bags are turned up and down to achieve an even mixing effect, no stirring device needs to be added, so that the manufacturing cost is reduced, the plunger valves are arranged in the color paste bags, the air in the color paste bags is extracted through the air suction cylinder to ensure that there is no air in the color paste bags, to prevent the color paste from deteriorating and to prolong the service life of the color paste.

METHODS AND APPARATUS TO AGITATE A LIQUID
20200238237 · 2020-07-30 ·

Method and apparatus to agitate a liquid are disclosed herein. An example apparatus includes a carrier having a base that includes a ridge extending from the base and a collar extending from the base. The example apparatus also includes a container supported on the base, the container movable between (A) a locked positon in which the ridge fixedly engages the container to non-rotatably couple the container to the base and (B) an unlocked position in which the container is disengaged from the ridge and the container is rotatable about the collar.

Agitation/defoaming method and agitation/defoaming device

[Problem] To provide a agitation/defoaming method and device with which both of uniformity in dispersion of object to be processed and reduction of air bubbles can be achieved with high precision. [Solution] Provided is a agitation/defoaming method for producing orbital and spin motions of a container containing object to be processed by a device provided with orbital and spin drive motors that can independently control the velocities of the orbital and spin motions. Both defoaming and agitating treatments with high precision can be achieved by respectively performing a reverse rotation superimposition processing, wherein the rotational frequency of the spin drive motor is obtained by superimposing the first rotational frequency in a direction opposite to the direction of the orbital motion on the frequency of the orbital motion, and a same rotation superimposition processing, wherein the rotational frequency of the spin drive motor is obtained by superimposing the second rotational frequency in the same direction as the direction of the orbital motion on the frequency of the orbital motion, at least once.
