Product Name – Indicator paper, pH 3.8 – 5.3 Indicator Quantity/Pack Size – 10 books Form – Paper strips Grade – Laboratory grade Application – pH testing in acidic range (3.8-5.3)
Product Overview
This pH 3.8-5.3 indicator paper delivers precise acidity measurements within a narrow range, making it essential for experiments requiring high accuracy in mildly to moderately acidic solutions. Each strip undergoes strict quality control to ensure consistent color transitions at the specified pH thresholds. The paper features a rapid response time, with visible color changes occurring within seconds of contact with the test solution. Designed for laboratory use, the strips maintain stability under standard storage conditions and resist degradation from ambient humidity. The 10-book pack provides an economical solution for frequent testing, with each book containing easily dispensable strips. The indicator uses a proprietary dye formulation that minimizes false readings from common contaminants. Color comparison is simplified through the included reference chart, which displays distinct hue variations at 0.1 pH unit intervals. This product meets international standards for pH indicator accuracy and is manufactured under ISO-certified conditions. The paper’s non-bleeding properties prevent dye transfer during handling, while its neutral background ensures optimal color contrast for visual interpretation.
FAQs
1. How quickly does this indicator paper show results after contact with a solution?
The color change becomes clearly visible within 2-5 seconds of contact with the test solution, allowing for immediate pH assessment.
2. Can this paper be used for testing solutions outside the 3.8-5.3 pH range?
No, this indicator is specifically formulated for the 3.8-5.3 range and will not provide accurate results outside these parameters. For broader ranges, consider using universal pH paper.
3. What is the shelf life of these indicator strips when stored properly?
When kept in the original packaging at room temperature away from direct sunlight and moisture, the strips maintain their accuracy for up to 24 months from the date of manufacture.
4. Are these strips affected by common laboratory solvents like ethanol or acetone?
The indicator paper is designed primarily for aqueous solutions. Organic solvents may alter the dye response or damage the paper matrix, potentially leading to inaccurate readings.
5. How should I dispose of used indicator strips?
Used strips can be disposed of with regular laboratory waste, though it’s recommended to follow your institution’s specific chemical waste disposal protocols if the strips have been in contact with hazardous substances.
