Product Overview
Sulphuric Acid 98% Chemically Pure Grade is a high-purity concentrated sulphuric acid intended for applications requiring tighter impurity limits than standard industrial acid.
It is suitable for laboratory, controlled manufacturing and chemical-processing applications where metal and inorganic contamination must be limited.
