In drug development, products or substances should maintain their chemical, physical and microbiological properties. Decelerating factors like API degradation can be minimized with pharmaceutical stability testing.

QACS provides pharma stability services based international protocol standards and tailor-made solutions. We test API’s, raw materials and final products in recommended environmental storage conditions like Temperature, Humidity, Light and Duration-Long term/Accelerated. Our GMP certified laboratory system allows us to evaluate product quality at specific time intervals under controlled and monitored conditions. Stability testing is supported by walk-in chambers, thermal stability chambers, humidity control climatic chambers and storage space.

Storage conditions are based on stability project needs.
