Automated method and apparatus for preparing bioprocess solutions
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.
