Blister pack leak test. View of a male technician carring out a leak test on a pharmaceutical blister pack. He is wearing a protective coat and cap. A blister pack containing drug tablets is being floated in a container containing blue liquid. Other blister packs can be seen at lower left. The technician is looking to see if the packaging is allowing any liquid to leak in. This test is necessary as blister packs containing drugs must be airtight in order to protect their contents from oxidation by air. The protective coat and cap are to maintain a sterile environment.
