Can vacuum pumping reduce air bubbles when degassing a liquid sample?

[bbobb]

hi, i would like to ask a rather general question. hope this is the right forum.

i have a liquid sample that i need to feed into a sample vial (see attached figure for how the sample looks like) through one of its chimneys. every part of the vial is circular in cross section. what i need to achieve is to feed the liquid into it such that there are minimal bubbles (0 bubbles is ideal) as i need to do some sensitive tests on the liquid. does anyone have an idea how i can do that?

pouring the liquid directly into a chimney is probably going to introduce a lot of bubbles. i was thinking along the line of letting the liquid settle out, then piping liquid from the bottom layers out through some kind of a straw and directly into the vial. however, this suction and expulsion action may also introduce air bubbles..

appreciate any input!

One possible solution is to use a vacuum pump to draw the sample from the container into the vial. This should help to reduce the amount of air bubbles that are created when pouring the liquid directly into the chimney. Additionally, you could also use filters or strainers to further reduce the amount of bubbles in the sample.
