Patent ID: 6998095

Claim:
A loop dilution apparatus, comprising: a first pump; a second pump; a first reservoir; a first loop having a predetermined volume; a second loop having a predetermined volume; and a multi-way valve, wherein the multi-way valve has a first configuration that connects: the first loop to a first solution source, the second loop to a second solution source, and the first pump and the second pump to a diluent source, wherein the first pump is operable to pump diluent from the diluent source into a first reservoir if the multi-way valve is in the first configuration, whereby the first loop is configured to receive a first solution from the solution source and the second loop is configured to receive a second solution from the second source if the multi-way valve is in the first configuration, and wherein the multi-way valve has a second configuration that connects: the first loop to the second loop, the first pump to a first end of the connected loops, and the second pump to a second end of the connected loops, whereby the first pump is configured to pump diluent from the diluent source into the connected loops if the multi-way valve is in the second configuration.
