Pall Corporation is expanding its line of Kleenpak Aseptic Connectors with two new sizes, 1/4- and 3/8-inch. The new sizes enable vaccine manufacturers to apply the safety and efficiency benefits of instant aseptic connections throughout more of their disposable operations to help speed time to market and comply with good manufacturing practices. Pall revolutionized the aseptic connection process by shortening the time needed for connection from 15 minutes to seconds when it introduced its 1/2-inch Kleenpak Connector. The addition of the two new Kleenpak Connector sizes increases flexibility to implement aseptic connections in more applications to improve disposable processing efficiency. This is especially important to complex vaccine production, which often requires a greater number of connection steps.
