WebThe proposed processes cope with this challenge by (1) freeze-drying the drug product in the syringe in an orientation in which the product is closest to the heat source, or (2) freeze-drying the drug product outside the syringe in a metal tube. The latter requires filling the freeze-dried product subsequently into the dual-chamber syringe. WebPump down the chamber to its lowest pressure. Put a vacuum gauge on the chamber. Valve off the chamber so the pump is disconnected and isolated from the chamber, and the chamber is sealed tight. Note the leak rate, either by reading it on a vacuum gauge that determines leak rate, or by creating a time vs. pressure graph.
