Component processing is a source of risk and variability, especially for loose particulate and silicone oil that can compromise quality, putting patients at risk. You can simplify your drug development strategy and streamline manufacturing by selecting cartridge plungers and lined seals in a ready-to-use format.

World-class cartridge components are manufactured for consistency and quality. So why not rely on the experts? Our industry-proven Westar® component processing reduces the risk of variability and its potential effects on drug quality, safety and efficacy. Westar cartridge components can help reduce the risk of product loss and failures.

Here is what you receive with Westar components:

 

  • Validated particle levels in specified size ranges.
  • Enhanced device functionality because of the optimized silicone level on the plungers.
  • Excellent re-seal properties to meet multi-dose requirements.
  • Lower levels of potential extractables, a result of steam sterilization.
  • The confidence that your drug cartridge components are manufactured from market-proven elastomer formulations.

You can choose Westar cartridge components in ready-to-use or ready-to-sterilize formats for flexibility in operations. With either choice, your components are supported by detailed technical knowledge documentation packages.

Cartridge plungers can be provided in Westar RS and Westar RU formats. Cartridge components can also be inspected by West's Envision™ system. Lined seals for glass cartridges are manufactured as laminated rubber sheeting, which provides customers with the best physical and chemical properties. West is able to provide cartridge seals that meet your needs whether it is a single or multi-dose application.
