Ensure Lab Accuracy with NIST-Traceable pH Buffers

About this item

Apera Instruments AI1108 pH Calibration Buffer Solution Kit ensures precise pH and ORP electrode calibration for laboratory use in India. This kit features NIST-traceable buffer solutions (pH 4.00 and 7.00, 8 oz each) and a 4 oz bottle of 3M KCL soaking storage solution, all manufactured in an ISO 9001:2015 certified facility with ISO 17025:2017 accreditation. The values are accurate to +/- 0.01 pH at 25°C, traceable to NIST Standard Reference Materials (SRMs), ensuring reliable results for critical lab applications.

The buffers are color-coded for quick identification and double-sealed for maximum integrity. Each unopened bottle carries a 2-year expiration from the manufacture date. The HDPE bottles are designed for safe handling and storage. This kit is ideal for research labs, educational institutions, and quality control departments requiring consistent and accurate pH measurements.

Imported directly for Indian laboratories, this Apera Instruments kit offers superior accuracy compared to generic alternatives. All customs duties and GST are included in the listed price, with delivery via ExpressBox tracked shipping. Certificate of analysis is available upon request, and MSDS documents are downloadable for safety compliance.

Key Features

  • Reported values are accurate to +/- 0.01 pH at 25 °C and are traceable to NIST Standard Reference Materials (SRMs).
  • Produced in an ISO 9001:2015 certified facility using high-purity reagents, deionized water and certified analytical balances in a temperature controlled environment.
  • color-coded for quick identification.
  • Double-sealed. 2-year expiration from manufacture for an unopened bottle.

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

  • Prepare for Calibration — 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.
  • Calibrate with pH 7.00 Buffer — 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 4.00 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.
  • Store Electrode Properly — 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.
