1. An instrument for sampling biological fluids, comprising:

  • a) a primary line having an inlet for receiving a biological fluid;

    b) a fluid reservoir for storing an anticoagulant or rinsing fluid;

    c) a waste container for storing waste received from said primary line;

    d) a plurality of sample collection chambers attached to a plurality of collection lines for selectively collecting a plurality of fluid samples from said primary line;

    e) at least one pump for selectively pumping each of;

    i) fluid from said primary line to said waste container,ii) fluid from said primary line to each of said sample collection chambers independently,iii) fluid from said fluid reservoir to said primary line;

    f) a valve for selecting access between each of;

    i) said primary line and said waste container,ii) said fluid reservoir and said primary line,iii) optionally said fluid reservoir and said waste container; and

    g) a microprocessor operably linked to memory and a power source, wherein said microprocessor instructs said selective pumping of said at least one pump and instructs selection by said valve.
