Hello /sci/, I have a question regarding chemistry instruments. Kind of a grey area question between this board & /adv/. Are these worth anything? Am I able to clean them and sell them? Or do I just huck them in the recycle bin? I can't unscrew the top off these vials, but there are others. Very small ones, and plastic test tubes. I also have a small box of plastic syringes - no needles. Is there a chemist out there that knows anything about this stuff? Thanks
