Fwd: Durham tube question

<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.) An answer or 
direction to a source would be greatly appreciated. Thanks!>


Put the inverted Durham tubes in the bigger test tubes first. Then 
dispense the broth, cover the tubes and autoclave.
