Why do we neutraize a glass rod by heating?

Question asked by: knowitall

The reason for this is not to neutralise but to sterilise, that is kill any bacteria or impurities that may be on the end of the glass rod.

It ensures the end is clean and therefore that anything there won't impact upon the results of the accuracy of any tests we do that involve that glass rod.
