Apparatus for discharging contents of a sealed container

Apparatus for transferring fluid from a test tube having an interior sealed by a resilient, self-sealing, reusable, repuncturable closure at one end, said apparatus comprising:

• means for puncturing said resilient, self-sealing, reusable closure for establishing a fluid inlet path and a fluid discharge path, said fluid discharge path having an inside diameter;
• means for delivering fluid, said fluid delivering means having an outside diameter and extending through said fluid discharge path;
• means for pressurizing the interior of the test tube for discharging fluid contents through said delivering means;
• and
• means for venting the interior of the test tube, said venting means being configured for preventing accidental discharge of the fluid contents of the test tube when the test tube is subjected to temperature variations, said venting means maintaining sufficient resistance to venting for pressurizing the interior of the test tube for discharging the contents of the test tube, said venting means for providing continuous venting at least when the interior of the test tube is not pressurized.
