The following test is used to check the integrity at the Freeze Dry System
collection chamber. The figure below points out potential areas to locate a leak:
1. Remove the stopper from the side of the chamber and place a flat gasket
and a freeze dry flask over the connection port.
2. Fill the collection chamber with approximately 2 inches of water, enough
to cover all fittings. Replace the collection chamber lid and turn on the
vacuum pump. Allow the vacuum pump to run for approximately 5 to 10
seconds. (If the vacuum pump is left on, the water will begin to boil and
the test will not be effective). Look inside the chamber for any bubbling
while the pump is running and after you shut the pump off.
