Precision pH 4 Calibration Standard (Colorless) by Inorganic Ventures – Multiple Sizes
Ensure the utmost accuracy and reliability in your laboratory's pH measurements with the Inorganic Ventures pH 4 Calibration Standard (Colorless). This premium-grade Potassium Hydrogenphthalate buffer is meticulously formulated as a certified reference material (CRM), specifically designed for lab professionals who demand precision and compliance. Available in a comprehensive range of sizes, each bottle benefits from Inorganic Ventures' innovative Transpiration Control Technology (TCT) for an outstanding 5-year shelf life from the date of manufacture when stored in its sealed TCT bag.
This clear, colorless pH 4.00 buffer is manufactured by Inorganic Ventures, a global leader in analytical standards. Production adheres to the stringent requirements of ISO 17034 (Reference Material Producer) and ISO 17025 (Testing and Calibration Laboratories) accreditations. This dual certification ensures the highest possible quality, consistency, and competence in the manufacturing and testing of the standard. Furthermore, this pH 4 buffer is fully traceable to NIST Standard Reference Materials (SRMs), providing irrefutable evidence for your laboratory's quality control systems and supporting accreditation requirements.
The revolutionary Transpiration Control Technology (TCT) packaging is a key feature, protecting the integrity of the standard. This technology provides a 5-year shelf life for unopened products stored in the sealed TCT bag. Once the TCT bag is opened, the standard maintains its certified values for up to one year, offering flexibility and significant cost savings by minimizing waste due to expired reagents and simplifying inventory management.
