Stability testing & storage
of pharmaceuticals.
For ensuring product quality throughout the entire shelf life—including for controlled substances and radioactive drugs.
Would you like to confirm that your products remain stable throughout their shelf life? Stability testing is a key component of pharmaceutical development and quality control. It provides evidence that a drug maintains its efficacy, purity, and safety throughout its entire life cycle. Without valid stability data, approval by authorities such as the EMA or FDA is not possible.
We test whether your products remain stable throughout their shelf life – reliably, in compliance with GMP and ICH, and using state-of-the-art technology.
Our services at a glance:
- Chemical and microbiological analyses: All relevant tests are performed in-house – precisely and reliably.
- Under all climatic condition: Stability studies in accordance with ICH guidelines, adapted to different climate zones and storage conditions.
- Photostability: Additional light stability tests to evaluate the effects of UV and visible light on product quality.
- Narcotics and radioactive drugs: Specialization in stability testing of narcotics and radiopharmaceutical preparations under the strictest safety conditions.
GMP- and ICH-compliant storage:
In addition to testing, we offer the option of storing your medicinal products under controlled climatic conditions. We ensure that temperature and humidity are continuously monitored and documented.
Our data provides you with a reliable basis for development studies, quality control, and regulatory dossiers. This allows us to create transparency and security—from the early development phase to market launch.
Your advantage: With CUP Contract Labs, you can be sure of reliable stability studies and storage conditions—for regulatory compliance, the highest quality, and successful approval.
