Wait 5 seconds or 5 minutes after testing—the colors still match. Each 15-foot roll of paper is supplied in a plastic dispenser with color chart and convenient tear-off tab.
Hydrion Ultrafast 0–14 pH Test Paper
For the rapid determination of pH values from 0–14. The Ultrafast test set consists of two 15-foot rolls of pH paper—the Insta-Chek 0–13 and the Ultra-Sharp 12.5–14 test papers. The Insta-Chek 0–13 is a general- purpose, immediate response, wide range paper with a different bright color for each pH value from 0–13. The Ultra-Sharp 12.5–14 test paper is ideal for determining high pH values. It exhibits crystal clear color changes, from a bright blue at 12, through green at 13 and finally to sunny yellow at 14. Used in tandem, these two papers span the entire pH scale from 0–14. Refill package contains five 15-foot rolls of the Insta-Chek 0–13.

Hydrion Pocket pH Set
Consists of seven types of pH paper that, when used together, cover the entire pH range from 0 to 14. Includes one roll of Insta-Chek 0–13 pH paper—the ultimate in wide range, general purpose, pH paper. It displays a different bright color for each pH value from 0–13. Also includes six rolls of narrow range paper, each paper covering a pH range of 1.5–2.5 pH units with a sharp color change of each half pH unit. Narrow range papers supplied include 1 to 2.5, 3 to 5.5, 6 to 8, 8 to 9.5, 10 to 12, and 12.5 to 14. Each 15-foot roll of paper is supplied in a plastic dispenser case with color chart and convenient tear-off tab. Set is packaged in a durable carton for permanent storage.
Hydrion 1–12 pH Test Strips
A low cost vial of pH paper (in strips) that covers the full range of 1 to 12 pH units. A color change will occur for each pH unit and a color matching chart is affixed to the side of the vial. Two charts are provided on each vial, i.e., 1–6 pH and 7–12 pH. 100 strips per vial. You will want to consider this paper as a substitute for traditional litmus paper. The sharply-defined color for each pH unit will provide the student with a good deal more accuracy than just acid or base as is the case with litmus paper.
