ABSTRACT:
A liquid sampling device having a tubular section of flexible material having a wall defining a lumen for passage of liquid, and a rigid valve member positioned in the lumen and having a sealing surface for engaging against an inner surface of the tubular section and preventing passage of liquid through the lumen. The tubular section is pressed against the valve member to deform the wall of the tubular section and permit passage of a liquid sample between the valve member and tubular section. The valve member is rotated to a position with at least a portion of the sealing surface of the valve member spaced from the inner surface of the tubular section to permit passage of liquid between the valve member and tubular section.
