Aurical Company, Home of the gold Standard, manufactures and provides the Aurical 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 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. Bottle packaged standard is reliable for only one use. The remainder must be discarded. The Aurical proprietary package overcomes this defect. 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 test.
