Product Description
When it comes to precise pH measurements, accuracy is non-negotiable. The Buffer Solution, Traceable to SRM from NIST (1.99004.0001 | Merck) is designed for laboratories, researchers, and educators who demand reliability in their calibration processes. Whether you’re standardizing a pH meter for routine lab work or conducting critical research, this buffer solution ensures your readings are consistent and traceable to NIST standards.
Available in pH 4, pH 7, and pH 10 variants, these solutions are formulated to meet the highest analytical standards. Each bottle is carefully prepared to maintain stability and accuracy, making them ideal for educational institutions, pharmaceutical labs, and industrial quality control. The traceability to NIST SRM (Standard Reference Material) guarantees that your calibration is aligned with globally recognized benchmarks.
For students and researchers, using a NIST-traceable buffer solution eliminates guesswork in experiments. Educators can confidently demonstrate pH calibration techniques, knowing the results will be reproducible. The 30 x 30 mL pack size offers convenience for frequent use without the hassle of frequent reordering.

Why pH Calibration Matters
pH meters are sensitive instruments that require regular calibration to maintain accuracy. Over time, electrodes drift due to wear, contamination, or storage conditions. Using a traceable buffer solution ensures that your meter is recalibrated to a known standard, reducing errors in critical applications like:
- Environmental testing (water, soil analysis)
- Pharmaceutical and food industry quality checks
- Academic research and student experiments
- Industrial process control
Without proper calibration, even minor deviations can lead to incorrect conclusions, wasted resources, or failed experiments. This buffer solution provides the stability needed for long-term reliability.
Choosing the Right pH Buffer
Selecting the correct buffer depends on your application:
- pH 4 Buffer: Ideal for acidic range calibration, commonly used in food testing and wastewater analysis.
- pH 7 Buffer: The neutral reference point, essential for general lab use and biological samples.
- pH 10 Buffer: Critical for alkaline range calibration, often used in chemical synthesis and cleaning product testing.
For comprehensive calibration, many labs use all three buffers to cover the entire pH spectrum. The Merck NIST-traceable series is a trusted choice for professionals who prioritize accuracy.
Storage and Handling
To maximize shelf life and performance:
- Store buffers at room temperature (15–25°C).
- Avoid exposure to direct sunlight or extreme temperatures.
- Keep bottles tightly sealed when not in use to prevent contamination or evaporation.
- Do not reuse buffer solutions once contaminated.
Proper storage ensures the solution remains stable for the duration of its shelf life, typically 12–24 months from manufacture.
Safety Considerations
While buffer solutions are generally low-risk, always follow standard lab safety protocols:
- Wear appropriate PPE (gloves, goggles) when handling.
- Avoid skin or eye contact. In case of contact, rinse thoroughly with water.
- Dispose of used solutions according to local laboratory waste regulations.
FAQs
What does “traceable to NIST SRM” mean?
It means the buffer solution’s pH value is directly linked to the National Institute of Standards and Technology (NIST) Standard Reference Materials, ensuring high accuracy and global recognition in calibration.
Can I use this buffer solution for medical diagnostics?
While it meets analytical grade standards, always verify with your institution’s protocols. For clinical diagnostics, ensure compliance with specific medical device regulations.
How often should I calibrate my pH meter?
For routine use, calibrate before each session or at least weekly. For critical applications, daily calibration with fresh buffer solutions is recommended.
Is this buffer solution compatible with all pH meters?
Yes, it is designed for universal compatibility with standard pH electrodes. However, always check your meter’s manual for specific buffer requirements.
Can I buy individual pH buffers (4, 7, or 10) separately?
This pack includes all three pH buffers (4, 7, 10) for comprehensive calibration. For individual bottles, check eqipped’s product listings or contact support.
