(This is my first post so sorry if I make a mistake)

Is there a way to perform a "decent" Winkler Titration to measure the dissolved oxygen concentration in a water sample without the special BOD bottles?

The special bottles ensure that there are no external oxygen bubbles when collecting the sample, but they're too expensive for me at $300 a piece. So I was wondering if there was some cheaper alternative that does not contaminate the sample too much.

Thanks in advance!

Any bottle with a tight stopper should work, as long as you are cautious.
