Hach, 1222249, Buffer Solution, pH 7.00, 500 mL

Hach pH 7.00 buffer solution is a neutral calibration standard for pH meters and compatible glass pH electrodes. It provides a nominal pH of 7.00 ±0.02 at 25 °C in a ready-to-use, colorless solution supplied in a 500 mL bottle. The standard is suitable for establishing the neutral calibration point before measuring environmental waters, process liquids, laboratory solutions and other aqueous samples. It can be used with Hach meters and other compatible instrumentation during single-point or multipoint pH calibration procedures. Traceability to NIST reference materials supports routine analytical quality assurance. The bottle format provides a convenient supply for repeated instrument checks in water-treatment facilities, quality-control laboratories and field-analysis programs. This product is calibration buffer, not a pH electrode or universal conductivity standard.
