High-Acidity Precision: Inorganic Ventures pH 1.68 Calibration Standard (PH-1.68 Series)
Achieve precise and dependable calibrations in the highly acidic range with the Inorganic Ventures pH 1.68 Calibration Standard (PH-1.68 series). This certified reference material (CRM) is expertly formulated for laboratory professionals working with applications requiring accurate pH measurements at very low pH levels.
Manufactured by Inorganic Ventures, a trusted leader in analytical standards, this pH 1.68 (at 25°C) buffer is typically prepared from high-purity Potassium Tetraoxalate in a stable aqueous matrix. Production strictly adheres to ISO 17034 (Reference Material Producer) and ISO 17025 (Testing and Calibration Laboratories) accreditations, ensuring the highest quality, consistency, and reliability. This standard is fully traceable to NIST Standard Reference Materials (SRMs), vital for your laboratory's quality assurance programs and regulatory compliance.
Inorganic Ventures' innovative Transpiration Control Technology (TCT) packaging safeguards the integrity of this standard. TCT provides an exceptional 5-year shelf life from the date of manufacture when the product is stored unopened in its sealed TCT bag. After opening the TCT bag, the standard generally maintains its certified value for up to one year, provided it is handled and stored correctly to prevent contamination.
