HR2-413-**** Refers to the reagent number in the kit.For example, Solubility & Stability 2 reagent number 1 = HR2-413-01
The formulation pH is the final, actual measured pH at 25°C. Buffered reagents are titrated with NaOH or HCl. The water control and reagents without buffer are not titrated. The measured pH range of the eight unbuffered reagents A1-H1 is 5.6 - 6.2.
HR2-413-01 100% Deionized Water specification is Type 1+ ultrapure water, 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL).
