  • TypeEnvironmental & Mechanical
  • NIST-traceable calibration ensures reliable pH 7.00 readings
  • 24-month shelf life reduces replacement frequency
  • 20 mL single-use vials prevent cross-contamination
  • 20-pack quantity supports high-volume lab workflows

Calibration Buffer Solution, 20 mL × 20

This buffer solution provides a precise pH 7.00 reference for calibrating laboratory pH meters and electrodes. Each package contains twenty individual 20 mL plastic containers. The solution is formulated to laboratory grade and includes a NIST-traceable calibration certificate. It has a shelf life of twenty-four months.

Suited for routine meter calibration

Technicians who need a certified, neutral reference for daily instrument verification will find this pack convenient. Users requiring different pH values, larger single volumes, or non-buffered reagents should look elsewhere. The product is not intended for applications outside standard pH calibration procedures.

NIST-traceable calibration certificate included

The certificate confirms the pH 7.00 value against national standards, supporting compliance and audit requirements. This traceability is the decisive factor for regulated environments. Without it, the solution would not meet documented quality-assurance protocols.

Questions about this item

Does the 20 mL plastic container fit standard calibration-cup holders?

Each 20 mL plastic bottle is sized for typical lab cup holders; verify your holder’s inner diameter before use.

What is the correct sequence to open and use a bottle without contaminating the NIST-traceable pH 7.00 buffer?

Break the tamper seal, pour the needed volume into a clean beaker, recap immediately, and never return used solution to the bottle.

When must the 24-month shelf-life buffer be replaced?

Replace any bottle after 24 months from manufacture or sooner if the solution appears cloudy or the pH drifts from 7.00.
