Product Overview
AVS TITRINORM® pH buffer solutions are meticulously formulated for high-precision calibration of pH meters and electrodes. Available in three critical pH values—4.00, 7.00, and 10.00—these buffers ensure accurate measurements across acidic, neutral, and alkaline ranges. Each 30 ml sachet is sealed to prevent contamination, offering convenience and consistency for routine lab work. The analytical-grade purity guarantees minimal lot-to-lot variation, while the ready-to-use format eliminates preparation errors. Designed for stability at 20 °C, these buffers maintain their specified pH values over extended periods, reducing recalibration frequency. Their compatibility with most laboratory glassware and electrodes makes them a versatile choice for research, quality assurance, and industrial applications. The sachet packaging minimizes waste and exposure to atmospheric CO₂, preserving buffer integrity. Whether for educational demonstrations or professional lab environments, these buffers deliver reliable performance, backed by rigorous quality control standards.
FAQs
1. What is the shelf life of these pH buffer sachets?
When stored unopened at room temperature, the buffers retain their specified pH values for up to 24 months from the date of manufacture. Always check the expiration date on the packaging.
2. Can these buffers be used with semi-micro pH electrodes?
Yes, the 30 ml sachet volume is sufficient for calibrating semi-micro electrodes without requiring large sample quantities, ensuring minimal waste during the process.
3. Are these buffers traceable to NIST standards?
AVS TITRINORM® buffers are manufactured under ISO-certified processes and are traceable to primary reference materials, ensuring compliance with international metrological standards.
4. How should I dispose of used buffer solutions?
Neutralize the buffers with a compatible acid or base before disposal, following your institution’s chemical waste protocols. The sachets themselves can be rinsed and recycled where facilities exist.
5. Do these buffers require temperature compensation during calibration?
The pH values are standardized at 20 °C. For accurate results, allow the buffer and sample to equilibrate to the same temperature or use automatic temperature compensation (ATC) if your meter supports it.
