Oakton (WD-35653-02) pH 7.00 Pouches 20-Box
pH 7.00 Calibration Pouches – 20-Box
The Oakton WD-35653-02 delivers pH 7.00 calibration solution in convenient single-use pouches, standardized against NIST-certified references for guaranteed accuracy. Each pouch is premixed and ready to use, eliminating preparation time and contamination risk. With ±0.01 pH accuracy at 25°C, these are the solution for high-precision calibration when you need it most.
Why Professionals Trust Oakton pH 7.00 Buffers
NIST-Traceable Accuracy
Every batch standardized against NIST-certified pH references, ensuring ±0.01 pH precision at 25°C for reliable calibration you can document
Single-Use Convenience
Individual pouches eliminate cross-contamination and degradation from repeated bottle opening, perfect for field work and mobile testing
Premixed and Ready
No mixing, no waiting, no guesswork. Tear open and calibrate immediately with solution that's been quality-tested and freshness-dated
Lab-Grade Stability
Formulated for consistent performance across temperature ranges with ±1% accuracy at 25°C, meeting demanding QC and compliance requirements
Field-Ready Format
Compact pouches fit in any field kit or toolbox, making on-site calibration practical without lugging large bottles or mixing equipment
Freshness Guarantee
Each pouch clearly dated so you know exactly when it was manufactured, protecting the integrity of your calibration protocols
Universal pH Meter Calibration
The Oakton WD-35653-02 pH 7.00 buffer pouches are compatible with all pH meters and electrodes requiring neutral-point calibration, including Oakton, Hanna, Thermo Scientific, Mettler Toledo, and other laboratory and field instruments. Ideal for water quality testing, aquaculture monitoring, environmental sampling, food and beverage quality control, hydroponics, pool and spa maintenance, pharmaceutical manufacturing, and any application requiring NIST-traceable pH calibration documentation. Box of 20 pouches provides consistent calibration for teams and high-volume testing operations.
Oakton buffer solutions are trusted by water quality professionals, lab technicians, and field operators who need verifiable accuracy backed by NIST traceability.
