A device is described for accurately transferring multiple individual fluids from multiple source containers into a single receiving container. Fluid flows from the multiple source containers through individual fluid conduits to a chamber having a single fluid outlet conduit. The fluid outlet conduit is in fluid communication with a single receiving container. A pressure conduit is in communication with the chamber for alternately creating positive and negative pressures in the chamber to cause fluid to flow from the individual source containers into the chamber, and to cause fluid flow from the chamber into the receiving container in response to commands from a controller.

A device for accurately transferring multiple individual fluids from multiple source containers to a single receiving container, in which fluid flows from said multiple source containers through individual fluid conduits to a chamber having a chamber fluid outlet conduit in fluid communication with the single receiving container, the chamber also having a pressure conduit, the invention comprising: first occlusion means for selectively preventing fluid flow from each of said individual fluid conduits to said chamber; pressure means for selectively creating positive and negative pressures in said chamber to control the rate of fluid flow through said chamber; second occlusion means for selectively occluding fluid flow from said chamber outlet fluid conduit to said receiving container; and control means for controlling said first and second occlusion means and said pressure means, said control means causing said first occlusion means to allow fluid to flow through at least one of said individual fluid conduits while causing said second occlusion means to prevent fluid flow into said receiving container and simultaneously p1 causing said pressure means to create a negative pressure in said chamber to precisely control the amount of fluid flow into said chamber, said control means further causing said first occlusion means to prevent fluid flow through all of said individual fluid conduits after a predetermined amount of fluid has been delivered to said chamber, said control means then further causing said second occlusion means to allow fluid to flow from said chamber through said outlet conduit while simultaneously causing said pressure means to create a positive pressure in said chamber to force fluid from said chamber into said receiving container.
