Premium pH Buffer Solutions for Accurate Calibration
A buffer solution is defined as an aqueous solution that resists significant changes in pH upon dilution or the addition of small amounts of strong acid or base, provided the temperature remains constant. These solutions are crucial in a wide variety of chemical applications where maintaining a nearly constant pH value is necessary, such as in analytical chemistry and the calibration of pH meters.
The LOVIBOND pH Buffer Solution set (pH 4, 7, and 10), offered in 500mL variations, provides the essential acidic, neutral, and alkaline standards required for precise pH electrode calibration and control. Regular calibration is vital to determine the condition of the pH electrode and ensure consistently accurate measurement results.
Unmatched Quality and Traceability
LOVIBOND buffer solutions are manufactured to meet the highest quality standards in the industry. These solutions are produced in controlled batches using ultrapure water that meets standard requirements and undergo stringent quality testing throughout the production process to ensure freedom from contamination before and after bottling.
Key quality features include:
• NIST Traceability: All LOVIBOND pH buffers are traceable to NIST (National Institute of Standards and Technology) standard reference materials, ensuring the highest level of accuracy and reliability. This full traceability is essential for trusted accuracy in professional environments.
• Precision Formulation: The solutions are specifically formulated for electrochemical applications, delivering consistent and reproducible measurements.
• Secure Packaging: The solutions are sealed with a pressure-sensitive seal, an outer safety seal, and a torque-tested cap to maintain uncontaminated integrity throughout their shelf life. Unopened bottles typically have a shelf life of up to 2 years.
Convenient Use and Storage:
This set includes the three most common pH buffer solutions (pH 4, pH 7, and pH 10), which are conveniently color-coded for easy distinction: pH 4 is typically red, pH 7 is yellow, and pH 10 is blue.
For accurate measurements, a 2 or 3 point calibration is the suggested procedure, using buffers above and below the expected sample pH value. During calibration, pH 7 should ideally be calibrated first.
Important Usage Guidance:
• Avoid Contamination: Always decant small amounts of buffer into separate cups for calibration and NEVER pour used buffer solutions back into the original bottle to preserve the integrity of the standard.
• Storage: pH buffer solutions should always be stored in a cool, dry place. For optimal performance, the sealed bottles should be stored between 5 °C and 25 °C.
Ideal Applications:
These precision calibration standards are crucial for ensuring the proper function of pH electrodes across a wide range of industrial and laboratory settings.
• Calibration of pH meters and controllers.
• General chemical analysis.
• Water testing applications including:
◦ Drinking Water Treatment
◦ Waste Water Treatment
◦ Boiler Water
◦ Cooling Water
◦ Pool Water Control
• Food and Beverage Industry.
• Chemical and Pharmaceutical Industries.
