In the bubble emission test according to ASTM F2096, the integrity of packaging or sterile barrier systems is evaluated by applying internal pressure. For this purpose, the packaging film is punctured on one side using a needle, internal air pressure is applied, and the package is submerged in water. In our setup, a second needle and a digital manometer are used to directly measure the internal pressure.

To validate the procedure and to set the required internal pressure, a hole is intentionally introduced into the packaging using a 250 µm needle. The internal pressure is then adjusted until a continuous stream of air bubbles is produced.

We are pleased to perform leak testing of your packaging using the bubble emission test.
