Test chambers leakage rate

Vacuum leakage test for chamber and condenser verification of the system integrity, through a leakage rate test. A leakage rate of less than 10 mbarL/s was chosen. 

The leakage rate is determined in an empty lyophilizer with running of the condenser cooling. Before starting the test phase it is recommended to evacuate the lyophilizer (chamber and condenser) several hours (e.g., 4h) to remove the gas (e.g., below 10 mbar). After stopping the vacuum pumps the test phase begins when pressure is stabilized and has reached 10 mbar.
