Abstract
A sample testing system includes a plurality of sample tubes, each sample tube coupled to a pumping chamber, a pressure control subsystem and a flow control subsystem. The pressure control system includes a first dynamic pump equipped to induce pulsatile pressure in a mass of pumping fluid coupled to the pumping chambers. The flow control subsystem includes a mean flow pump equipped to generate a flow of sample fluid in a plurality of flow loops. Each of the flow loops conducts the flow of sample fluid between the mean flow pump and one of the sample tubes. The pumping chamber couples pressure from the pumping fluid to the sample fluid.
