    is there any mistake?

    Laboratory benches are made of granite. In this way, they are not shaken easily and degradation mechanisms is prevented. In addition,the changing colours isnít seen in case of acid is spilled in the asid-base experiments.

    See above. You don't generally "shake" workbenches so I wonder if you mean that they're not easily broken. If "degradation mechanisms" is a technical phrase, then it needs to be followed by "are" (mechanisms = plural). However, I have removed "mechanisms" as I assumed that you simply meant that granite does not degrade easily.
