Orion™ pH Buffer Individual Use Pouches

Single-Use NIST-Traceable pH Calibration Buffers for pH Meter and Electrode Calibration

Each pouch is individually labeled with catalog number, lot code and expiration date, supporting documentation and traceability required for GMP, GLP and ISO quality systems.

pH 4, 7, and 10 buffer pouches and solutions are color-coded for quick identification during calibration.

• pH 4 buffer pouches and solution are light red
• pH 7 buffer pouches and solution are yellow
• pH 10 buffer pouches and solution are blue

Redesigned pouches offer a rectangular shape to better accommodate electrodes placed directly into the pouch and 20 mL solution volume to ensure proper electrode immersion for accurate calibration.

Key Features

• pH buffers are traceable to NIST reference standards
• Each pH buffer pouch and solution is color-coded
• Each pouch is labeled with catalog number, lot code and expiration date
• Each pouch is easy to open with tear notches
• Each pouch is single use to reduce contamination risk

Workflow and Application Benefits

Orion pH buffer individual-use pouches simplify pH calibration procedures in both laboratory and field settings.

• Direct electrode calibration: Updated pouch design allows electrodes to be placed directly into the pouch for quick calibration steps.
• Quick identification during calibration: Color-coded buffers help technicians rapidly identify the correct standard during multi-point calibration procedures.
• Consistent calibration performance: Single-use pouches ensure each calibration uses fresh buffer solution, reducing variability caused by contamination or evaporation.
• Convenient calibration anywhere: Compact pouches are ideal for field testing, environmental monitoring and routine QA/QC calibration workflows.
