Test tubes!

I got a dumb question to ask. Do you use a specific tube for each test or do you use the same tube? I use a different one for each test.

I have misplaced some of my tubes, so I just use the same tube from time to time. I do make sure that they are thoroughly rinsed and dried to keep from throwing off the results though.

As long as they are cleaned and dried in between uses, it is fine. The testing is just indicator liquids, which won't absorb into the glass as long as they are not left in for long periods of time. Honestly, barely even cleaning them would still be fine, I know the tubes I use in my chem lab classes still have gunk in them and rarely do my experiments get thrown off.

Thanx everyone.
