Oakton (WD-35653-02) pH 7.00 Pouch
pH 7.00 Calibration Solution Pouch
NIST-traceable neutral buffer in single-use format for high-precision field calibration of pH meters and electrodes
Laboratory-grade precision in a field-ready format
NIST-Certified Reference
Every batch standardized against NIST materials, ensuring your Oakton pH meter calibrates to the same standard used by testing labs nationwide
Single-Use Pouch Design
Individual sealed pouches prevent cross-contamination and buffer degradation between uses—open, calibrate, dispose
±0.01 pH Tolerance
Holds 7.00 pH ±0.01 at 25°C, meeting the precision demands of laboratory protocols and regulatory compliance work
Freshness Dated
Clearly marked expiration ensures you're always calibrating with buffer that meets specification—no guesswork on shelf life
Works with all pH measurement systems
The Oakton WD-35653-02 pH 7.00 buffer is compatible with all brands of pH meters, electrodes, and probes requiring neutral point calibration. Use with Oakton pH testers, benchtop meters, portable instruments, and any electrode requiring two-point or three-point calibration routines. Ideal for field technicians calibrating water quality meters from Oakton, Hanna, Thermo, Hach, and other manufacturers.
When to use pH 7.00 calibration buffer
Initial Calibration
Always calibrate at pH 7.00 first as your neutral reference point before adding pH 4.00 or pH 10.00 buffers in multi-point calibration
On-Site Verification
Single-use pouches eliminate the need to carry bottles—pack what you need for the day's calibrations without spill or contamination risk
Instrument Verification
Use fresh buffer to verify meter accuracy before critical measurements or when regulatory protocols require documented calibration
Lab-Grade Accuracy
NIST traceability means your field readings hold up to the same standard as laboratory reference measurements
Water Testing Essential
Neutral pH 7.00 is the cornerstone calibration point for drinking water, wastewater, aquaculture, and hydroponics monitoring
No Waste, No Contamination
Single-use format means you never pour used buffer back into a bottle or worry about buffer degradation over time
