ISO Guide 34/17025 pH Buffers, Color, Inorganic Ventures

ISO Guide 34
ISO Guide 34 "General Requirements for the Competence of Reference Materials Producers" certifies that we meet every requirement for the competence in the very specific field of Reference Material Production. Accreditation to ISO Guide 34 involves not only technical competence and good quality management practices, but adds verification of critical production management specific to reference material producers. We've been accredited to Guide 34 longer than any other inorganic standards manufacturer.

These pH Standards are all certified reference material set in a water matrix for stability. These standards are Traceable to NIST and manufactured in accordance with our stringent Quality Assurance guidelines. Each pH Standard has 5 convenient sizes (250mL, 500mL, 1L, 4L, 10L bottles) and 3 colors (red, yellow, blue).

These standards are available with Transpiration Control Technology (TCT), a new packaging system that drastically extends the shelf life of these standards. Transpiration Control Technology (TCT) puts you in control of the expiration date. Do not open the TCT bag until you are ready to use the product. TCT extends the shelf life of your custom standard by up to three years without compromising accuracy. The one-year expiration date doesn’t start until you open the bag.
