What grade of pH calibration buffer solution should I choose for lab work?

Choose the grade that matches your application. The Apera Instruments AI1108 kit offers NIST-traceable solutions accurate to +/- 0.01 pH at 25°C, suitable for analytical and titration work. Check the stated assay percentage and form (e.g., liquid buffers) on the product label to confirm fit for your specific lab needs.

How should pH buffer solutions be stored?

Store the Apera Instruments pH buffer solutions in their original airtight, double-sealed HDPE containers away from moisture and incompatible substances, in a cool, dry place. Because these solutions can absorb moisture and degrade, keep the caps sealed tightly between uses to preserve the stated purity and accuracy.

Is this Apera Instruments pH calibration kit suitable for Indian lab conditions?

Yes, this kit is designed for precise calibration and is suitable for Indian lab conditions. The buffers are manufactured under strict ISO certifications, ensuring accuracy and reliability. While heat and humidity can affect some lab reagents, these sealed solutions are formulated for stability, and the included KCL solution helps maintain electrode health.

What is the expiration date for the Apera Instruments pH buffer solutions?

Unopened bottles of the Apera Instruments AI1108 pH Calibration Buffer Solution Kit have a 2-year expiration from the manufacture date. Once opened, use within the period indicated on the packaging or as per standard laboratory practice for maintaining solution integrity.

Can I get a Certificate of Analysis for the Apera Instruments pH calibration kit?

Yes, a Certificate of Analysis (CoA) can be obtained upon request for the Apera Instruments AI1108 pH Calibration Buffer Solution Kit. MSDS documents are also downloadable for safety and compliance purposes, ensuring you have all necessary documentation for your laboratory.

Why choose this product

Precision Calibration for Indian Labs

Apera Instruments AI1108 pH Calibration Buffer Solution Kit delivers NIST-traceable accuracy, essential for precise pH and ORP measurements in research, education, and quality control across India. Manufactured under stringent ISO certifications, these buffers use high-purity reagents and deionized water, ensuring +/- 0.01 pH accuracy at 25°C. The color-coded, double-sealed HDPE bottles guarantee integrity and a 2-year shelf life for unopened products. This imported kit provides a reliable alternative to local options, ensuring your sensitive equipment performs optimally.

Who Should Choose This Kit & Who Should Look Elsewhere

This kit is ideal for laboratories, research facilities, educational institutions, and quality control departments requiring highly accurate and traceable pH calibration solutions. It is perfect for calibrating Apera pH/ORP electrodes and other compatible meters. Individuals or labs needing only a single pH point or less precise calibration may find this kit over-specified. For applications requiring specific buffer solutions not included (e.g., pH 10), or for very basic field testing where NIST traceability is not critical, alternative single-point solutions might be more cost-effective.

How to use

Open the pH 4.00 and 7.00 buffer solutions and the KCL soaking solution. Ensure your pH/ORP electrode is clean and ready for calibration. Keep the bottles sealed when not in use to maintain solution integrity. — Prepare for Calibration
Rinse the electrode with deionized water. Immerse the electrode in the pH 7.00 buffer solution. Allow the reading to stabilize, then follow your meter's instructions to calibrate to pH 7.00. This step typically takes 30-60 seconds. — Calibrate with pH 7.00 Buffer
Rinse the electrode again. Immerse it in the pH 4.00 buffer solution. Allow the reading to stabilize, then calibrate the meter to pH 4.00. This second point calibration ensures accuracy across a wider range. — Calibrate with pH 4.00 Buffer
After calibration, rinse the electrode thoroughly. Store the tip immersed in the 3M KCL soaking solution to keep the glass membrane hydrated and prevent drying, ensuring electrode longevity and performance for future use. — Store Electrode Properly
