EXTECH INSTRUMENTS Buffer Pouches Pack (4, 7 & 10pH with Rinse Solution)

Ensure the accuracy and reliability of your pH meter with the EXTECH INSTRUMENTS Buffer Pouches Pack. This convenient set provides pre-measured, ready-to-use calibration and rinsing solutions, eliminating the hassle of mixing chemicals and ensuring consistent results every time. The pack is designed for simplicity and efficiency in laboratory, industrial, and educational settings where precise pH measurement is critical.

The kit includes a comprehensive selection of buffers: six individual pouches each of pH 4, pH 7, and pH 10 solutions. These fresh, pre-made buffers are essential for performing multi-point calibration, which verifies the linear response of your pH meter across its entire range. Accompanying the buffers are two pouches of specialised rinsing solution, used to clean the pH electrode before and after measurements to prevent cross-contamination between samples and buffer solutions.

Each pouch is user-friendly and practical. The design eliminates the need for separate storage cups—simply tear open the pouch, immerse the electrode, and calibrate. A helpful table printed directly on the buffer pouches displays the expected pH value relative to the solution's temperature, allowing for quick verification and ensuring your calibration accounts for thermal variation, a key factor in measurement accuracy.

Using these solutions helps maintain your electrode's performance and extends its lifespan by preventing residue build-up and contamination. The compact, foil-sealed pouches also guarantee solution freshness and longevity until the moment of use, providing peace of mind for quality control procedures, environmental testing, aquaculture, hydroponics, and any application requiring dependable pH analysis.
