Start Up Procedure
A. Read the previous section of Principle of Operation if unfamiliar with
device.
B. Soap volume is not critical, therefore a measured amount is not
necessary. The proper amount is that which is sufficient to create a
bubble. Simply pour a small amount of soap through the bottom nipple
to thoroughly cover the bottom of the flow cell and attach air source to
nipple (bottom nipple for pressure, top nipple for vacuum). Excessive
amount of soap may cause a continuous stream of bubbles to go up the
center tube at high flows.
