Product Overview
This pH 2.00 buffer solution is a high-precision calibration standard designed for laboratory applications requiring exact pH measurements. Formulated to a tolerance of ±0.01 at 25°C, it ensures reliable and reproducible results in analytical procedures. The Specpure® grade guarantees minimal impurities, making it suitable for sensitive instrumentation. As a NIST-traceable solution, it meets stringent quality control standards, providing confidence in calibration accuracy. The colorless formulation eliminates potential interference in optical measurements, while the stable pH value maintains consistency over time. Available in convenient pack sizes of 500ml, 1L, and 4L, this buffer solution offers flexibility for different laboratory needs. Its sealed packaging prevents contamination and extends shelf life, ensuring long-term performance. The solution is compatible with most pH meters and electrodes, making it a versatile choice for routine calibration and quality assurance protocols.
FAQs
1. What is the shelf life of this pH 2.00 buffer solution?
The unopened solution typically maintains its specified pH value for 24 months from the date of manufacture when stored properly. Once opened, it should be used within 6 months for optimal accuracy.
2. Can this buffer be used with all types of pH electrodes?
Yes, this pH 2.00 buffer solution is compatible with most standard glass pH electrodes. However, for specialized electrodes like those designed for high-temperature or non-aqueous applications, compatibility should be verified with the electrode manufacturer.
3. How should this buffer solution be stored to maintain accuracy?
Store the unopened bottles at room temperature (15-25°C) away from direct sunlight. After opening, keep the bottle tightly sealed when not in use and avoid exposure to extreme temperatures or humidity.
4. Is this buffer solution suitable for food or pharmaceutical testing?
While the Specpure® grade indicates high purity, this buffer solution is primarily designed for general laboratory use. For food or pharmaceutical applications, additional certifications or grades may be required depending on regulatory standards.
5. What alternatives are available if I need a different pH value?
For calibration at different pH points, complementary buffer solutions such as pH 4.00, pH 7.00, or pH 10.00 are commonly used. These are available in similar Specpure® grades with NIST traceability for consistent calibration across the pH range.
