The Integra uses the same proven three spinning roller sealing head design as the standard PW Westcapper®. Now, a servo driven actuator will bring the sealing head to the vial and utilize a load cell to accurately provide proper sealing pressure. This functionality provides a quality seal despite variations in vial height.
A stoppered vial is a prevalent parenteral drug container closure system. The system however should not be considered integral until the rubber stopper is crimped firmly in place with sufficient compression against the vial, assuring all potential leakage is cut off at the seal interface. It is well understood that seal quality is critically important to maintaining sterility and stability of the drug product.
