ABSTRACT OF THE DISCLOSURE Apparatus for securing pump mechanisms to test tubes sealed by a closure such that the contents of the test tubes may be discharged without removing the closure. The apparatus includes a rack for holding a plurality of pump mechanisms, each of the pump mechanisms including a downwardly extending needle or the like for penetrating the closure of the test tube. The test tubes are arranged within a tray in a plurality of rows, and each row is sequentially advanced into position. As each row is in position, the pump mechanism is moved toward the row of test tubes to penetrate the test tube closures. The pump mechanisms thereafter released, the rack filled with a next series of pump mechanisms, the test tube array indexed, and the cycle of steps is repeated. The pump mechanism needles are initially imbedded in a protective packaging. The apparatus strips away the protec- tive packaging to expose the sharpened points or tips of the pump mechanism.
