1. Apparatus for providing at least one sample of a liquid contained in a pouch while mitigating the danger of contaminating the liquid in the pouch, the apparatus comprising:

  • an inlet tube having proximal and distal ends, and comprising a frangible barrier therein, between the proximal and distal ends, the proximal end connected to an inlet of a sterile sight chamber, the chamber comprising;

    a vent in the chamber wall fitted with a bacterial filter through which air can flow to and from the chamber; and

    an outlet;

    the inlet tube comprising a tube clamp thereon, wherein the tube clamp is a sufficient distance from the distal end to permit a sterile fluid connection to be established with the inlet tube at a point distal to the tube clamp;

    the tube clamp operable to regulate liquid flow through the inlet tube to the chamber when the connection is established and operable to block fluid flow in the absence of the connection; and

    a sample port comprising a hollow body with a distal end and a proximal end, wherein the distal end of the sample port is connected to the outlet of the chamber, and the proximal end is opposite the outlet.
