bubbling nitrogen

April 10, 2006 at 8:53 pm | | everyday science

The extent of chemistry chemistry that I do is making solutions of fluorescent dyes. But once in a while, I get to bubble N2 through a solution or something like that. I’m checking to see if this solution will bleach when de-oxygenated. But look how cool I am:


Isn’t that so cool? Here’s what my whole operation looks like (note the awesome poster in our lab):

  1. i think the worst part of this whole setup is that the star wars poster was actually MOVED from the upstairs lab to the new lab downstairs.

  2. hey, could someone suggest a liquid dye that bleaches when deoxygenated? I am a science research student looking to find a way to detect an deoxygenated environment that has a lot of nitrogen present… any suggestions?

  3. Hi, Thanks for this, it looks cool, and it is also very useful to see the essential parts of the process that researchers always avoid to describe in their articles, like the Star Wars poster. Now I see why my sample preparations kept failing. Sorry for not being able to give advice on dyes but I’m actually attempting something somewhat different like surface passivations. Wish you good luck. Cheers.
