This color-coded buffer pack has two vials, each containing ten capsules of
different pH value, four of pH 4.0 (red), four of pH 7.0 (green) and two
of pH 10.0 (blue). All values are accurate to within ±0.02 pH.

The dispenser contains one 15 meters (50 ft) roll of pH paper
and a color comparison chart; measures pH from 0 to 13 in 1 pH unit increments.
