AST's Vial Sealing System (VSS) is a benchtop, semi-automatic machine used for sealing or capping pharmaceutical vials and bottles with aluminum caps. The VSS provides complete and precise control of the container sealing or capping operations to ensure the highest quality vial seal. The system’s versatility allows for the processing of a wide range of vial or bottle sizes and finishes and is ideal for small batch processing of sterile pharmaceutical and biotechnology products.

The Container Closing System was designed with cGMP in mind. Its compact, aseptic design provides complete compatibility with cleanrooms, bio-safety cabinets, laminar airflow hoods, and aseptic isolator environments.

Consistent High-Quality Sealing

Proper application of the vial cap is critical to container closure integrity, sterility and stability of the drug product within the vial. The Vial Sealing System monitors critical parameters such as applied force prior to forming the seal on the aluminum skirt to ensure proper stopper compression during the sealing process. The system utilizes a free-spinning disk design that has been optimized to minimize the generation of particles during the sealing process and to form a pharmaceutically aesthetic seal.

Vial Sealing Process

The vials or bottles are manually placed on the machine by the operator. Once placed, the sealing process is initiated, and the sealing head moves down to compress the vial stopper until the closed-loop compression force feedback confirms the operator programmed compression setting is achieved. With the stopper compressed the vial is rotated and the free-spinning disk gently forms the aluminum skirt of the cap around the neck of the vial. This sealing process maintains the compression of the rubber stopper, generates fewer particles and provides a pharmaceutically aesthetic seal without the witness marks common to jaw style crimpers.
