Squeeze bottles of toluene

A list of small, useful things (links):
Again, an open invitation to all interested in writing a blog, a hobby that will bring you millions thousands hundreds tens of dollars joy and happiness. Send me a link to your post, and I'd be happy to put it up.


  1. The resistance of PCBs to degradation means that the children of today's environmental analytical chemists will be identifying and quantitating Aroclors in samples using a GC with an electron capture detector. The EPA might no longer exist.

  2. Roman does such a great job on those infographics, I love them

  3. CJ - you might want to go to a title like "2mL Transfer Pipettes" or "Scoopula" (my personal favorite). Unlike
    your links and postings which are infinitely useful, LDPE that squeeze bottles are made of do not stand up well against toluene and usually show degradation within days.

    1. Not all squeeze bottles are LDPE! For hydrocarbons and DCM where I work, we have to use something else (I forget what), due to exactly this problem. Although maybe you are right, because the 'something else' is borderline useless as a squeeze bottle.


looks like Blogger doesn't work with anonymous comments from Chrome browsers at the moment - works in Microsoft Edge, or from Chrome with a Blogger account - sorry! CJ 3/21/20
