CalibrationX manufactures and provides the world's most accurate Low-Level Conductivity Standards. These standards are essential for accurate conductivity measurement in purified water. High accuracy is required for pure water and water for injection in pharmaceutical manufacturing.
Methods for the preparation of aqueous conductivity standards at these levels are well established. However, traditional bottle packaging is not adequate for protection and use. This is because carbon dioxide in the air dissolves in the standard and changes the value; in essence, making bottle packaged standards reliable for only one use. The remainder will have a different value due to exposure to air and carbon dioxide in particular. CalibrationX' proprietary package overcomes this challenge. The flexible impervious package has a spout valve, which prevents room air from entering the container. This means that the contents remain stable until the container is empty allowing the full 500-mL for multiple calibrations and tests.
Each container of each lot is individually tested. The actual value and tolerance is the mean and two standard deviations of the lot testing. These values are traceable to NIST SRMs or the NIST Absolute Conductivity Method. Please follow the care instructions for each product included in your package to ensure maximum accuracy and satisfaction.
