Product Overview
The Dosatest nonbleeding pH test strips offer precise pH measurement across the 2.0-9.0 range, designed specifically to prevent color bleeding that can distort readings. Each strip provides clear, easy-to-interpret color changes corresponding to pH levels, ensuring reliable results for critical laboratory applications. The nonbleeding formulation maintains color integrity even when wet, eliminating the common issue of dye transfer that compromises accuracy in standard pH strips. These strips are manufactured with high-quality indicator papers that respond quickly to solution pH, delivering consistent performance across multiple tests. The 2.0-9.0 range covers most common laboratory requirements, from acidic to alkaline solutions, making them versatile for various experimental setups. The compact strip format allows for convenient single-use testing without requiring additional equipment or calibration. Each pack contains 100 individually cut strips, providing sufficient quantity for repeated testing while maintaining cost-effectiveness. The strips are packaged to protect against moisture and contamination, preserving their sensitivity until use. Their laboratory-grade quality ensures compatibility with standard testing protocols, while the nonbleeding property makes them particularly suitable for applications where precise color matching is essential.
FAQs
1. What is the shelf life of these nonbleeding pH strips?
The strips typically maintain their accuracy for 2-3 years when stored in their original sealed container away from moisture and direct sunlight. Always check the expiration date printed on the packaging for specific batch information.
2. Can these strips be used for testing semi-solid samples?
These strips are designed for aqueous solutions. For semi-solid samples, you would need to first create a liquid extract or suspension before testing to ensure accurate pH measurement.
3. How do these compare to digital pH meters in terms of accuracy?
While digital meters offer higher precision (typically ±0.01 pH), these nonbleeding strips provide reliable results within ±0.5 pH units, which is sufficient for most qualitative and semi-quantitative laboratory applications where rapid screening is required.
4. What should I do if the color doesn’t match the chart exactly?
For borderline colors, compare under natural daylight or a standard white light source. If uncertainty persists, consider testing a fresh sample or using a narrower-range pH strip for confirmation.
5. Are these strips affected by temperature variations during testing?
The strips themselves are temperature-stable, but pH measurements can be temperature-dependent. For critical applications, allow samples to reach room temperature before testing or note the temperature for reference.
