  • Publication number: 20240181409
    Abstract: An automated bioprocess solution preparation apparatus includes a first mixing chamber containing at least one ingredient for a bioprocess solution, a first port and a second port for a fluid to enter the mixing chamber, and a third port for a liquid bioprocess solution to exit the mixing chamber. The apparatus further includes an array of tubing for fluid flow within the apparatus, a sensor arranged to measure a property of the liquid bioprocess solution exiting the mixing chamber, a first valve associated with the first port, and a second valve associated with the second port. When the property meets or exceeds a threshold value, the apparatus is operable to perform at least one of: closing the first valve to block the fluid from entering the mixing chamber through the first port, and opening the second valve for the fluid to enter the mixing chamber through the second port.

  • Patent number: 11925913
    Abstract: An automated apparatus for preparing a liquid bioprocess solution includes at least one mixing chamber having a lower port and an upper port for fluid to enter the at least one mixing chamber, an array of tubing for fluid flow within the system, a plurality of valves provided within the tubing, and a mixing controller configured to cause the automated apparatus to perform a series of sequential mixing steps causing the preparation of the liquid bioprocess solution from a dry ingredient. The series of sequential mixing steps include opening a first valve associated with the lower port to provide fluid to the at least one mixing chamber through the lower port, and after a predetermined amount of elapsed time, closing the first valve and opening a second valve associated with the upper port to provide fluid to the at least one mixing chamber through the upper port.

  • Publication number: 20240033659
    Abstract: A filter unit for a mixing apparatus includes a hydrophilic filter and a hydrophobic vent filter. The hydrophilic filter is configured to receive a fluid including a liquid and gas. The hydrophilic filter is further configured to sterilize the liquid. The hydrophobic vent filter is configured to receive the gas from the hydrophilic filter. The hydrophobic vent filter further includes a vent and a membrane configured to separate an interior of the filter unit from an exterior of the filter unit, the gas being vented from the filter unit by flowing across the membrane and out of the vent. In some embodiments, the filter unit further includes a defoaming device configured to receive gas, foam comprised the liquid containing trapped gas, and some of the liquid from the hydrophilic filter and is further configured to release at least some of the gas from the foam.

  • Patent number: 11097237
    Abstract: An automated method includes providing a dry ingredient to be reconstituted into a liquid bioprocess solution and controlling, by a processing circuit, all automated system including at least one mixing chamber, an array of tubing for fluid flow within the system, and a plurality of valves provided within the tubing, to automatically prepare the liquid bioprocess solution from the dry ingredient. Controlling the auto system may include performing a series of sequential mixing steps, the series of sequential mixing steps causing the preparation of the liquid bioprocess solution. The method mixing include taking one or more measurements during the preparation of the liquid bioprocess solution, wherein each step is triggered by at least one of a measurement decreasing below, equaling, or exceeding a measurement threshold. Each step may also include opening or closing, by the processing circuit, at least one of the plurality of valves.

  • Patent number: 10385301
    Abstract: A method of reconstituting a powdered cell culture media includes providing a mixing apparatus and providing a powdered cell culture media to the fluid chamber of the mixing apparatus, prior to introducing fluid to the chamber. The method further includes introducing fluid to the chamber through an influent port, wherein the influent port is tangentially oriented relative to an inner wall of the fluid chamber to thereby cause the fluid to follow the wall of the fluid chamber in a circular motion, creating a vortex flow in the fluid chamber by introducing fluid at a sufficient flow rate, and enhancing the vortex flow with a geometric fluid flow aid by further channeling the water around the wall of the fluid chamber, around the geometric flow aid. The method further includes continuing to introduce fluid to the chamber and collecting reconstituted fluid that exits the chamber through the effluent port.
