20140213934 | Specimen Collection Container Having a Fluid Separation Chamber - A specimen collection container having a separation chamber includes a first chamber, a second chamber, and a valve located between the first chamber and the second chamber. In an open position, the valve permits fluid communication between the first chamber and the second chamber. In a closed position, the valve maintains fluid isolation between the first chamber and the second chamber. A fluid stream passes from the first chamber to the second chamber through the valve permitting a predetermined volume of fluid to pass from the first chamber to the second chamber. When the predetermined volume of fluid passes to the second chamber, the valve transitions from the open position to the closed position so that additional fluid of the fluid stream received by the first chamber is maintained in the first chamber in fluid isolation from the predetermined volume of fluid contained in the second chamber. | 07-31-2014 |
