Re: Air bubbles prevent fluid flow inside a small hollow fiber.

Hi-

The less elegant solution would be, of course, to draw a partial vacuum 
on one end of the tube, and draw the water in, but we would all agree 
that that would "suck."

However, it seems so much like you are describing a capillary tube that, 
at first glance, just tipping it and raising one end slightly above the 
water line would automatically cause the water to enter via capillary 
action.

However, I do not know if this would work if the chamber is, 
indeed “filled” with water, not offering the air bubble anywhere to 
escape.

The only solution I know, which may be impossible in this situation, is 
to drain and dry the system, pull vacuum, and allow water to enter and 
fill the chamber (and tube) slow enough as to not generate any bubbles.

Or at least that is how we would do it in Georgia.
