OOOhh, I see.
So you have a pump and gravity to get the solution from the top basin to the sterile recieving container. Not as complicated as i thought it was going to be. You know how most of us muscle heads are. We can finish our masters but couldn't bleed a set of brakes to save our lives (i'm speaking for myself and those like me...lol)Go back up to the post where I posted the pic of the hand pump and filter.
The pump tube attaches to the side of the filter.
When you pump, its actually pumping air out.
This causes a vacuum to be created within the receiver flask.
The oily solution in the pre filtration container located on top is then pulled through the filter into the receiver.
