Stability Testing

With over 14,000 ft2 storage capacity and over 14 ICH and custom conditions, Irvine has the capability to help design stability studies tailored to product needs.

Partner with Irvine's Stability Testing Team

For the quality control and security your projects demand, all cGMP validated environmental and photostability chambers are monitored 24 hours a day by a computer-based Environmental Monitoring System. Our walk-in, reach-in, UV/visible and fluorescent photostability chambers are supported by back-up chambers, a reserve generator and an electronic notification system.

We have the latest Stability Laboratory Information Management System (LIMS) to ensure compliance. The system accommodates sophisticated sample management, as well as allows the stability department to generate cumulative reports.

At Irvine, our mission is to provide our clients with outsourcing solutions that make their drug development priorities possible.
