Product Overview
The pH 2-4.5 indicator paper is a highly sensitive, lab-grade testing tool designed for accurate acidity measurement in the low pH range. Each strip undergoes precise calibration to ensure consistent color transitions, providing reliable results for critical applications. The paper is manufactured with high-quality, non-bleeding dyes that resist fading, ensuring long-term stability during testing. Its rapid response time allows for immediate pH determination without the need for additional equipment. The compact book format protects the strips from environmental contamination while offering convenient tear-off access. This indicator paper is particularly effective in detecting subtle pH variations within the 2-4.5 range, making it indispensable for applications requiring precise acidity control. The color chart included with each book features clear, distinct gradations for easy interpretation. The paper’s neutral background enhances color contrast, improving readability even in low-light conditions. Its chemical resistance ensures accurate readings in various sample types without degradation. The indicator paper maintains its sensitivity throughout the entire book, with each strip performing consistently from first to last use.
FAQs
1. How quickly does this pH indicator paper show results?
The color change occurs within 1-2 seconds of contact with the test solution, allowing for immediate pH determination.
2. Can these strips be used for testing semi-solid samples?
For semi-solid samples, first create a liquid extract by mixing with distilled water, then apply the solution to the indicator paper.
3. What’s the shelf life of these pH indicator books?
When stored properly in the original packaging away from moisture and direct sunlight, the books maintain their accuracy for up to 24 months from manufacture date.
4. How should I store these indicator books for maximum longevity?
Keep the books sealed in their original packaging, stored in a cool, dry place between 15-25°C, away from volatile chemicals and humidity sources.
5. What makes this specific pH range (2-4.5) important for testing?
This narrow acidic range is critical for applications requiring precise control of strong acids, where small pH variations can significantly impact chemical reactions and processes.
