摘要： A fluid delivery system including a filter for filtering solid particles from a liquid sample, the filter including a first filter member configured to filter solid media from a liquid sample, a second filter member fluidly connected to the first filter member, and a third filter member fluidly connected to a downstream end of the second filter member. The second filter member is configured to filter relatively smaller solid media from the liquid sample than the first filter member, and the third filter member is configured to filter relatively larger solid media from the liquid sample than the second filter member. In various aspects, the system includes a displacement-type plunger needle to draw sample fluid from a vial, a cantilevered carousel for rotatably supporting an array of sample holding vials, and a support for supporting the carousel. Method of using the fluid delivery system are also disclosed.
