We use standard disposable polypropylene (PP) 50mL centrifuge tubes with a PP screw-cap for several sample preparation procedures. Everything is well unless there's an organic solvent involved and the tubes have to be shaken in the procedure (think Quechers). In that case, every 5 samples or so there's one leaking which is very annoying. I want to look for an alternative which closes better.
Can anyone recommend similar recipients compatible with organic solvents like acetonitrile, ethyl acetate, (m)ethanol and hexane (at room temperature) which you can close and shake without leaking? Looking at solvent compatibility charts with polymers, I believe PP is still the best choice for this solvent selection?
