Traceable pH Buffer Standards

Daigger Traceable® pH Buffer Standards (CRM) are 100% compatible with all instruments and probes. Accuracy for the Traceable® Buffer at 25°C is ±0.010 pH—the most precise available. Certified Reference Materials meet Federal/State/local agencies’ strictest mandates and deliver exact calibration results for any pH meter.

Certification documentation is supplied for every Traceable Certified Reference Material. A2LA ISO 17025 (Calibration Laboratory) and ISO Guide 34 (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy. Additional accreditation includes ISO 31 (content) and ISO 35 (statistical analysis). ISO 9001 ensures that world-class product standards for Materials are always met.

Select values are manufactured to IUPAC (International Union of Pure and Applied Chemistry) formulation. All Certified Reference Materials feature resistance to temperature changes and long-term buffer stability.

To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory.

Available in  a standard 16 oz bottle or the One-Shot (100 mL) single-use bottle. The One-Shot buffer eliminates the concern about external container contamination by calibrating in the standard's vial.

Each bottle is supplied with individual temperature compensation chart, traceability information, and Traceable® Certificate.

Key Features:

  • Accuracy at 25°C is ± 0.010pH
  • Available in One-Shot™ single-use containers
  • Certified Reference Material
  • Traceable® Certificate comes with each bottle
