Product Overview
Buffer tablets, pH 7 LR, are pre-formulated to deliver a stable pH reference solution for accurate calibration of pH meters, electrodes, and other analytical instruments. Each tablet dissolves quickly in distilled or deionized water to produce a standardized buffer solution with a precise pH of 7.00 at 25°C. The LR (Laboratory Reagent) grade ensures high purity and consistency, minimizing errors in measurements. These tablets are designed for convenience, eliminating the need for manual weighing or mixing of powdered buffers, thus reducing the risk of contamination or human error. The uniform composition guarantees reproducibility, making them ideal for laboratories where precision is critical. The tablets are chemically stable under normal storage conditions, ensuring long shelf life without degradation. Their compact form factor allows for easy storage and portability, while the pre-measured dosage simplifies workflows in busy lab environments. Whether used in educational settings, research facilities, or quality control labs, these pH 7 buffer tablets provide a reliable benchmark for maintaining instrument accuracy and ensuring compliance with standard testing protocols.
FAQs
1. How do I prepare a buffer solution using these pH 7 LR tablets?
Dissolve one tablet in 100 mL of distilled or deionized water at 25°C. Stir gently until fully dissolved to achieve a pH 7.00 buffer solution.
2. Are these tablets compatible with all types of pH meters?
Yes, these LR-grade buffer tablets are universally compatible with standard pH meters and electrodes, provided the meter is properly calibrated according to manufacturer guidelines.
3. What is the shelf life of these pH 7 buffer tablets?
The tablets remain stable for up to 24 months from the date of manufacture when stored in a cool, dry place in their original packaging, away from direct sunlight and moisture.
4. Can I use tap water instead of distilled water for preparing the buffer?
Tap water may contain impurities or minerals that can alter the pH, so it is not recommended. Always use distilled or deionized water for accurate results.
5. How do I verify the accuracy of the prepared buffer solution?
Cross-check the prepared solution with a freshly calibrated pH meter or use a secondary reference buffer to confirm the pH reading matches the expected value of 7.00.
