Product Overview
Total hardness indicator tablets LR are formulated for reliable water hardness analysis, offering consistent performance in titration-based testing. These LR-grade tablets dissolve rapidly in water samples, producing a distinct color change at the titration endpoint for accurate calcium and magnesium ion detection. The uniform composition ensures minimal variability between batches, making them suitable for repetitive testing in controlled environments. Each tablet is calibrated to react predictably with EDTA titrants, eliminating the need for manual indicator preparation. The stable formulation resists degradation from humidity or temperature fluctuations, maintaining efficacy throughout the shelf life. Designed for compatibility with standard lab equipment, these tablets integrate seamlessly into existing water testing protocols. The non-hygroscopic properties prevent clumping, ensuring precise dosage with every use. Whether for routine quality control or detailed research, these indicator tablets provide a cost-effective alternative to liquid indicators without compromising accuracy.
FAQs
1. How do these indicator tablets compare to liquid hardness indicators?
Tablets offer consistent dosage per test, eliminating measurement errors associated with liquid indicators. They also have longer shelf stability and are less prone to contamination during storage.
2. What is the recommended storage condition for these tablets?
Store in a cool, dry place below 30°C in the original container with the lid tightly closed. Avoid exposure to direct sunlight or moisture to prevent degradation.
3. Can these tablets be used with automated titration systems?
Yes, they are compatible with most automated titrators designed for water hardness testing, provided the system can accommodate tablet-based indicators.
4. What is the typical color transition observed during titration?
The solution transitions from wine-red to blue at the endpoint when titrated with EDTA, indicating complete complexation of calcium and magnesium ions.
5. Are there any safety precautions required when handling these tablets?
While generally safe, use standard lab practices: wear gloves and avoid inhalation of dust. The tablets are non-toxic but should not be ingested.
