This test determines if the source of a leak is in the drying chamber.
1. Remove the drying chamber or manifold.
2. Leave the gasket on and turn a large freeze dry flask upside down to cover
the connection port.
3. Start the Freeze Dryer and observe the vacuum indication. If the vacuum
indication is good, then the problem is in the drying chamber or manifold
and you should return to Section II, Gaskets, Tubing, Connections, Sample
Valves.
