PH4 Buffer Solution Clear NIST Standard (UKAS) 1ltr

The Buffer Solution pH 7.00 (Phosphate) is a NIST Standard Solution designed for effortless pH measurements. Ready for immediate use, each solution is easily identifiable by its color, streamlining the measurement process and minimizing errors. The high-quality and reliable buffer solutions, available in standard and color-coded variations, ensure accurate results for calibration and titration. Manufactured with a precision of ?0.02 pH units, these solutions are accurately standardized and labeled with lot-specific pH values at 20°C, maintaining traceability to NIST and BS 1647 standards. Packaged in HDPE containers (1L, 2.5L, and 5L quantities), these solutions prioritize product integrity and safe handling. Standard buffers cover the pH range from 2 to 10, while color-coded buffer solutions are available for pH 4, pH 7, and pH 10. The specifications include a colorless appearance, a pH of 7, a liquid physical form, and packaging in an HDPE plastic bottle with a quantity of 500 mL.
