Abstract
A sterile testing and dispensing apparatus is adapted for insertion into a sterile aseptically packaged container to permit the contents of the container to be tested and then dispensed. The apparatus includes a dispensing tube and a pH indicator removably received in the dispensing tube. When inserting the dispensing tube into the container through an appropriate hole or weakened area therein, the pH indicator is automatically exposed to the contents of the container. The pH indicator can then be withdrawn from the dispensing tube and visually examined to determine the presence or absence or spoilage.
