They are nice because you can seal them individually when you need to sample or if you are done with a reaction. I usually keep them connected to a mineral oil bubbler as well as connecting to nitrogen flow tubes.

How do we fix it? Any suggestion for what kind of super glues should we use? Or where could I just buy a new one?ChemGradhttps://www.blogger.com/profile/18304732744053614163noreply@blogger.comtag:blogger.com,1999:blog-4387100009341358284.post-86541197622149473352009-03-07T15:03:00.000+01:002009-03-07T15:03:00.000+01:00Read the box in the background...Clown Scientific!...Read the box in the background...<BR/><BR/>Clown Scientific!!!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4387100009341358284.post-48858661001121393832007-11-26T00:44:00.000+01:002007-11-26T00:44:00.000+01:00Is that regular plastic tube or silicon tube?Is that regular plastic tube or silicon tube?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4387100009341358284.post-52798163600125052992007-11-23T06:36:00.000+01:002007-11-23T06:36:00.000+01:00Yikes, this kind of makes me cringe!
