As a number one world CDMO, PCI Pharma Providers is a specialist and innovator in lyophilization and offers considered one of the largest lyophilization capacities during the industry.  With around twenty five several years of knowledge we provide the scientific abilities, global amenities, and scalable products that will help our shoppers obtain results.

Stoppering: This process entails sealing from the vials that contains the freeze-dried merchandise, and it performs a pivotal part in retaining the item's high-quality. Appropriate stoppering makes certain that the products stays uncontaminated and cost-free from exterior humidity, thus preserving its shelf existence.

three. Definition A stabilizing process through which a compound is first frozen and afterwards the amount of the solvent is lowered, first by sublimation (primary drying stage) and afterwards desorption (secondary drying phase) to values that could no more assist biological activity or chemical reactions.
