Apera Instruments 84 µS/cm (microsiemens) Conductivity Standard Calibration Solution, 8 oz

Description

Product Overview

The Apera Instruments 84 µS/cm Conductivity Calibration Solution is engineered to provide the highest level of precision for conductivity meter calibration across a broad range of applications. Formulated to deliver a target conductivity of 84 microsiemens per centimeter (µS/cm) with an accuracy of ±0.5 µS/cm at the standard reference temperature of 25 °C (77 °F), this solution serves as a reliable benchmark for both routine maintenance and rigorous quality‑control programs. Each 8‑ounce bottle is produced in a United States ISO 17025 accredited laboratory, ensuring that the solution meets stringent analytical standards and is consistent from batch to batch. The solution is NIST‑traceable, meaning its concentration is linked to national reference standards, providing confidence that measurements taken with calibrated instruments are both accurate and repeatable. The packaging includes clear labeling of the expiration date and lot number, facilitating straightforward documentation and compliance with laboratory record‑keeping requirements. Designed for compatibility with a wide variety of conductivity meters and electrode types, this calibration standard is a versatile tool for scientists, engineers, educators, and technicians who demand dependable performance.

Usage

In laboratory environments, the solution is used to verify the performance of conductivity meters before critical experiments, ensuring that data integrity is maintained throughout the analytical workflow. Industrial users employ the standard to calibrate process control instruments that monitor water quality, chemical concentrations, and electrolyte levels in manufacturing streams, helping to prevent costly deviations and maintain regulatory compliance. Educational institutions integrate the solution into teaching labs, allowing students to gain hands‑on experience with calibration techniques and understand the importance of traceability and accuracy in analytical chemistry. The solution’s stability at room temperature makes it suitable for field deployments where portable conductivity meters are used for environmental monitoring, such as assessing river water quality, groundwater contamination, or agricultural runoff. By following the manufacturer’s recommended calibration procedure—typically involving a simple rinse, immersion of the electrode, and a brief stabilization period—users can achieve reliable readings within minutes, minimizing downtime and maximizing productivity.

FAQ

What temperature should I use when calibrating with this solution?

The solution is calibrated to 84 µS/cm at 25 °C (77 °F). For the most accurate results, perform the calibration at this temperature or use a temperature‑compensated meter that can adjust the reading to the reference temperature.

How long does the calibration solution remain stable after opening?

When stored in a tightly sealed container at room temperature, the solution remains stable for up to six months. It is recommended to check the expiration date on the label and avoid contamination by using clean containers and pipettes.

Is this solution compatible with all types of conductivity electrodes?

Yes, the solution is formulated to work with a wide range of conductivity electrodes, including glass‑covered, solid‑state, and flow‑through designs. Always follow the electrode manufacturer’s cleaning and storage guidelines for optimal performance.

Can I request a Certificate of Analysis for my batch?

Absolutely. A Certificate of Analysis (COA) is available upon request and provides detailed information about the solution’s conductivity, temperature coefficient, and traceability to NIST standards.

What should I do if my meter does not read the expected 84 µS/cm?

If the meter deviates significantly from the expected value, first ensure the electrode is clean and properly immersed. Verify that the meter’s temperature compensation is active and set to 25 °C. If the issue persists, contact Apera Instruments technical support for troubleshooting assistance.
