Dear Mr. Nauman,

Due to its nature, glass is very prone to adsorb particles with charges (as can be the case of some metal ions in your reaction system). Maybe you can try using a polymeric vessel? However, the most suitable material for your reactor would also depend on the reaction conditions (such as T, P and other driving forces, like light or electricity). I believe strong polymers, such as fluoropolymers, should offer good temperature and chemical resistance to a wide range.

I think most of the polymers including Teflon are porous enough to adsorb (immobilize) some metals or metal salts or complexes. To my opinion an Hastalloy C (after proper cleaning-deactivation) or a Ti-reactor will do it.

I think Parr reactor (Ti coated reactor) is best option.........

You are right, but this is not the cheapest option with Parr or other reactors. You can also use Ti inserts, which fit in the common (Hastalloy) reactor in order to minimize wall-effect.
