PH Test Paper (PH 1-12)

Product Description

This colorimetric indicator test paper provides wide-range pH measurement for liquid formulations across an interval from pH 1 to 12. Impregnated with chemical indicators, the paper produces distinct visual color transitions at each full pH unit for direct comparison against an accompanying reference color chart. It is used during compounding for rapid pH verification, formulation adjustment, and in-process quality testing of aqueous solutions, oral liquids, suspensions, and topical preparations.
