Lyophilization removes water from a preparation under vacuum, leaving a stable cake that tolerates transit and storage far better than a solution. That stability is the reason the format is standard across the Sterling catalogue.
Stability is not immunity. Heat, light and repeated temperature swings all work against a lyophilized product over time. The general guidance across the catalogue is consistent: store vials refrigerated at 2–8 °C, protect them from light, and keep them sealed until use.
For partners holding inventory, the practical implications are simple. Receive stock into refrigerated storage promptly, keep it in original packaging for light protection, and rotate on release date using the batch reference — the final sequence of every reference encodes when the batch was released.
Product-specific guidance is printed with each product and listed on its catalogue page. When in doubt, the batch reference connects you to the release record and its handling notes.
