Sodium Standard Solution is required for Ion Selective Electrode (ISE) calibration in laboratory and field analysis.
Sodium Standard Solution is required for verification of Ion Selective Electrode (ISE) in laboratory and field analysis. The concentration value of the solution is 0.0435 mol/L ± 0.0004 mol/L Na⁺. The volume of each bottle is 500 mL. The solution is traceable to NIST standard reference materials. Good care and calibration of Ion Selective Electrode are important for reliable ISE measurements. Ready-to-use Standard Solution is supplied in an airtight package to guarantee the shelf-life.
Storage conditions
It is required to store the solution at the following temperature: 10 °C - 25 °C. It is recommended to protected the solution from direct sunlight. After opening, the expiration date is 3 months.
