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 to flow from the chamber into the receiving container in response to commands from a control means in the device.

A device for transferring material comprising: a source container; a receiving container; a conduit connecting said source and receiving containers; a chamber having a chamber outlet in communication with said receiving container; first occlusion means for selectively preventing movement of said material from said conduit to said chamber; pressure means for selectively creating differential pressures between said chamber and one of said source and receiving containers to control the movement of material into and out of said chamber; second occlusion means for selectively preventing movement of material from said chamber outlet 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 material to move through said conduit while causing said second occlusion means to prevent material from moveing into said receiving container and said control means also causing said pressure means to create a pressure differential between said chamber and said source container to cause material to move from said source container to said chamber, said control means further causing said first occlusion means to prevent material movement through said conduit after a predetermined amount of material has been delivered to said chamber, said control means then further causing said second occlusion means to allow material to move from said chamber through said outlet by causing said pressure means to create a positive pressure differential between said chamber and said receiving container to force material from said chamber into said receiving container.
