Automated system for adding multiple fluids to a single container

A method for transferring fluids from multiple source containers to a single receiving container, comprising the steps of:

• providing a transfer chamber in fluid communication between said source containers and said receiving container, each source container having a separable fluid communication line connected to said transfer chamber which is initially subject to a removable occlusion force, said transfer chamber and said receiving container also having a fluid communication line therebetween which is initially subject to a removable occlusion force;
• selecting an amount of one of said fluids to be transferred;
• generating a signal indicating said amount of said fluid to be transferred;
• transferring said selected fluid from its source container to said chamber under the influence of a pressure differential and by removing the occlusion force between said source container and said transfer chamber;
• measuring the amount of said fluid in said chamber;
• generating a signal indicative of the actual amount of said selected fluid present in said chamber;
• terminating transfer of said fluid when said actual amount of said fluid present in said chamber is equal to or greater than said selected amount by again subjecting said fluid communication between said source container and said transfer chamber to an occlusion force;
• and then
• transferring said fluid from said chamber to said receiving chamber under the influence of a pressure differential and by removing the occlusion force between said transfer chamber and said receiving container.
