Alternative to API test tubes?
Not that type of plastic. Polypropolene is pretty tough stuff and it’s very clear. This chart http://www.engineeringtoolbox.com/polypropylene-pp-chemical-resistance-d_435 ..html shows that it gets mostly 1’s (excellent) for most stuff. It does poorly with the acetone’s and solvents and stuff that melts most other plastics though. We don’t use any of that in our test kits though.. just don’t let your wife near them when she’s cleaning the polish off her nails…. or you if you’re into that. LOL Some of my other test kit brands have plastic test tubes and work fine with those kits and with API’s chemicals.
