The Choice for Serum and Lyophilized Drugs
Advanced pharmaceutical elastomer design and technology is the key to manufacturing stoppers that ensure the integrity of drug packaging and drug delivery systems. For instance, many of our stoppers are designed with a locking feature to prevent them from dislodging from the vial – a simple but critical innovation.
Protecting Drugs from Contamination
West FluroTec® barrier film can help protect drugs from contamination by reducing interaction between stopper and drug. Westar® processed stoppers are delivered ready-to-sterilize or ready-to-use – shortening prep time and boosting efficiency. Together, FluroTec and Westar provide safety, speed and simplicity.
Improved Filling Line Performance
West’s low moisture/low extractable stoppers are especially suited to lyophilized products. Our single-vent igloo stoppers improve filling-line performance by eliminating the processing interlocks typical of double-vented stoppers, and our LyoTec™ stoppers prevent other processing snags, including stoppers sticking to lyophilization chamber shelves.
