Calibration Solutions (Liquid)

Calibration solutions are specialized liquids or mixtures used to ensure the accuracy and precision of analytical instruments. They have a known concentration or property value, providing a reliable reference point for:  

• Verification: Confirming an instrument is operating within acceptable limits.  

• Adjustment: Correcting any deviations (or "drift") from the expected readings.

Calibration solutions are essential for a wide range of instruments and applications, including:

• pH meters: Solutions with precise pH values like 4.01, 7.00, and 10.01.  
• Conductivity meters: Solutions with specific conductivity levels.  
• Spectrophotometers: Solutions used to calibrate absorbance or transmittance readings.
• Titration equipment: Solutions with known concentrations for standardizing titrants.

Key characteristics of calibration solutions:

• Traceability: Their values are often traceable to national or international standards.
• Stability: They maintain their stated values over a defined shelf life.
• Accuracy: They are prepared with high-purity chemicals and methods.
