Product Overview
Buffer tablets, pH 4 LR, are specially formulated to provide a stable and accurate reference point for pH meter calibration. These high-purity tablets dissolve quickly in distilled or deionized water, creating a consistent pH 4 buffer solution essential for maintaining the accuracy of laboratory pH measurements. The LR (Laboratory Reagent) grade ensures minimal impurities, making them suitable for general lab applications where precision is critical. Each tablet is designed to deliver a standardized concentration, eliminating the need for manual weighing and reducing the risk of errors. The compact tablet form allows for easy storage and handling, while the long shelf life ensures reliability over extended periods. Whether used in educational labs, research facilities, or quality control environments, these buffer tablets offer a convenient and cost-effective solution for routine pH calibration. Their uniform composition guarantees reproducible results, which is vital for experiments requiring strict pH control. The tablets are compatible with most pH meters and electrodes, making them a versatile choice for a wide range of laboratory setups.
FAQs
1. What is the shelf life of these pH 4 LR buffer tablets?
The shelf life is typically 2-3 years when stored in a cool, dry place in their original packaging.
2. Can these tablets be used with any pH meter?
Yes, they are compatible with most standard pH meters and electrodes designed for lab use.
3. How do I prepare the buffer solution using these tablets?
Dissolve one tablet in 100 ml of distilled or deionized water to prepare the pH 4 buffer solution.
4. Are these tablets suitable for high-precision applications?
While they are LR grade, for ultra-high precision, consider analytical-grade buffer solutions.
5. What is the difference between LR and AR grade buffer tablets?
LR (Laboratory Reagent) grade is suitable for general lab use, while AR (Analytical Reagent) grade offers higher purity for critical applications.
