Lovibond 726146 pH 7.00 Buffer Solution, 500 mL | NIST Traceable Certified Calibration Buffer for pH Meters | Yellow Color-Coded

Lovibond 726146 pH 7.00 Buffer Solution – 500 mL NIST Traceable Calibration Buffer

The Lovibond 726146 pH 7.00 Buffer Solution is a certified, NIST-traceable calibration standard designed for accurate calibration of pH meters and pH electrodes. Supplied in a 500 mL bottle, this color-coded yellow buffer solution provides a precise pH value of 7.00 ± 0.015 at 25°C, making it the ideal neutral reference point for routine pH meter calibration.

Manufactured using certified reference materials traceable to the National Institute of Standards and Technology (NIST), this buffer solution delivers dependable accuracy and repeatability for laboratory testing, water treatment facilities, environmental monitoring, industrial processing, research applications, and educational institutions.

Its bright yellow color allows for quick identification during calibration procedures, helping reduce errors and improve efficiency.

Why Use a pH 7.00 Buffer Solution?

A pH 7.00 buffer serves as the neutral calibration point and is commonly used for one-point, two-point, and three-point pH meter calibrations. It is often the primary reference solution used to verify meter accuracy and electrode performance.

Common applications include:

• Drinking water testing
• Wastewater treatment
• Environmental monitoring
• Laboratory analysis
• Industrial process control
• Agricultural testing
• Aquaculture monitoring
• Educational and research laboratories
