The Quasaar Stability Center

The Quasaar Stability Center offers flexible, large-scale storage solutions, including the capability to store bulky packaging units such as palletized goods and bulk materials. In addition to conducting ICH stability studies, we also support aging studies — for example, on finished medicinal products, active pharmaceutical ingredients (APIs), raw materials/excipients, medical devices, and combined products. In this context, we also offer studies on the tightness and permeability of packaging materials.

We provide refrigerated and frozen storage conditions (5 °C / -20 °C) as well as special storage conditions upon request.

Beyond product storage, Quasaar offers a wide range of additional stability services, including transport validation and logistics support (e.g., transport simulation) in compliance with regulatory requirements. We are capable of performing stress tests under conditions ranging from -20 °C to 150 °C.

The climate control systems are state-of-the-art, qualified according to GMP and DIN ISO standards, and equipped with failure protection. All HVAC units are installed in a redundant configuration. The emergency concept includes access to an external power generator.
