Certified Reference Materials (ISO 17025 and 17034)

For the highest level of quality assurance in pH Calibration, trust our VeriSpec® line of Certified Reference Materials. Our ISO 17025 and 17034 Accreditations allow us to provide products that have undergone rigorous evaluations of manufacturing methods, quality control, stability, and homogeneity. As a result, a certificate with the specified property value, uncertainty, and traceability is available with every bottle. (see the example below)



***Note: the certified value and uncertainty shown above are an example. Actual values may vary.

All three of our quality control laboratories are now accredited to ISO/IEC 17025 for competence in laboratory testing and ISO 17034 for competence of reference material producers of VeriSpec® pH Buffer Certified Reference Materials.
