ABSTRACT:
The application discloses a test vial including a test article for immersion into a fluid medium, a sealed chamber which contains the fluid medium, and an open chamber which is external to the sealed chamber and which supports the test article. The sealed and open chambers define a barrier which isolates the fluid medium from the test article. The open chamber is covered by a closure. Retaining means are positioned on the closure and cooperatively support the closure in a first position and cooperatively receive the closure in a second position. The closure has a means for penetrating the barrier and for injecting the test article into the fluid medium when the closure is moved from the first position to the second position while maintaining the sealed chamber in a sealed condition upon movement of the closure from the first position to the second position.
