After a Melting point determination, why can't you re-use the solidified substance and capllary tube for subsequent determination?

  • Chemistry -

    In reality you probably could, however it is not good science as it has been considered to be contamined or already used and a new substance or solution should be obtained. I know this is wasteful but, that is just how it is.

  • Chemistry -

    I don't think it is all that wasteful. Those tiny capillary tubes are IMPOSSIBLE to clean. Even if they could be cleaned who would trust them? You're right. Get a new one.
