SM>I am trying to figure out how Durham tubes are placed in fermentation tube
preparations. (Yes, I know, "upside down". What I want to know is how they are
placed in the broth without any trapped gas.)
DE>Try tilting the broth tube as much as you can while inserting or pushing the
Durham into it. Even if some gas is trapped, you'll still be able to notice the
difference.
SM>Thank you, Danial. I got (what I thought were) good results using that
method, but my instructor was less than satisfied.
