This array of chemical reagent standards has been specially formulated to suit specific testing needs of laboratories. Application of these reagents can also be noticed in different industries for checking conductivity and ph value of fluids. Application of low dosage of these reagents provides accurate testing result. Internal acid and internal base containing in this range of chemical reagent standards are instrumental in neutralizing external base and external acid respectively. Offered chemical reagent standards have been formulated under controlled temperature to keep their original properties intact for long period. This product range is cost effective.
