The Choice for Serum and Lyophilized Drugs
West’s advanced elastomer technology is the key to manufacturing stoppers that ensure the integrity and effectiveness of drug product 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.

West FluroTec^® and Westar^®: An Unbeatable Combination
West’s 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.
