Product Name – Buffer solution pH 9.2, Borate buffer, traceable to NIST, ready to use Quantity/Pack Size – 1LT, 500ML Form – Liquid (ready-to-use solution) Grade – Analytical (NIST-traceable) Application – pH calibration, buffer preparation, enzymatic assays
Product Overview
This NIST-traceable borate buffer solution (pH 9.2) is pre-formulated for immediate use in laboratory applications requiring precise pH control. The ready-to-use liquid eliminates the need for manual preparation, ensuring consistency and reducing contamination risks. Its analytical-grade purity guarantees reliable performance in sensitive assays, enzymatic reactions, and calibration procedures. The buffer’s stability is maintained through rigorous quality checks, making it ideal for repetitive or high-throughput workflows. The borate-based composition provides excellent buffering capacity in the alkaline range, resisting pH shifts even with minor temperature fluctuations or dilution. Packaged in high-density polyethylene (HDPE) bottles to prevent leaching or degradation, this solution is compatible with most labware and instrumentation. Whether used in research, quality control, or routine testing, its traceability to NIST standards ensures compliance with international metrological requirements, offering confidence in experimental reproducibility.
FAQs
1. What is the shelf life of this borate buffer solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature (15–25°C). Once opened, use within 6 months for optimal accuracy.
2. Can this buffer be autoclaved for sterile applications?
Autoclaving is not recommended, as it may alter the pH or introduce contaminants. For sterile use, filter through a 0.22 µm membrane under aseptic conditions.
3. Is this buffer compatible with protein-based assays?
Yes, the borate buffer is suitable for most protein assays, but verify compatibility with your specific reagents, as some proteins may precipitate at pH 9.2.
4. How does NIST traceability benefit my experiments?
NIST traceability ensures the pH value is verified against primary standards, minimizing systematic errors and improving the reliability of your calibration or assay results.
5. What alternatives exist for pH 9.2 buffering?
Alternatives include glycine-NaOH or ammonia buffers, but borate offers superior stability and lower toxicity. For non-NIST applications, generic borate buffers may suffice.
