Product Overview
- Series ID PHA-SERIES
Supported Applications
The Omega PHA-Series consists of pre-mixed pH calibration solutions designed for the maintenance and verification of pH measurement systems. These liquid standards provide a known reference point to ensure sensor accuracy during routine instrument checks.
Operating Conditions & Performance
This series provides specific, stable pH values required for calibrating sensors across different acidity and alkalinity ranges. The solutions are formulated as pre-mixed liquids ready for immediate use in calibration procedures without requiring dilution or preparation by the end user.
Available Calibration Points
The series includes variants corresponding to specific pH levels:
- pH 4.01 (PHA-4)
- pH 7.00 (PHA-7)
- pH 10.01 (PHA-10)
Additionally, the series offers DI water variants for rinsing or zero-point checks:
- DI Water (PHA-DI)
Configuration Options
The PHA-Series is available in multiple container sizes and packaging configurations to accommodate different laboratory volumes and usage frequencies. The product line includes standard bottles as well as gallon-sized containers for higher-volume applications.
Packaging Options
- Standard bottle size (e.g., PHA-4, PHA-7, PHA-10)
- Gallon container size (indicated by the -GAL suffix in part numbers such as PHA-4-GAL and PHA-7-GAL)
Specialized Variants
The series includes specific model codes for distinct formulations:
- PHA-DI: Deionized water solution.
- PHAB-PH and PHAB-DI: Variants designated with the PHAB prefix, available in pH standard and DI configurations respectively.
- PHA-10-CAL-PH: A specific variant of the pH 10 calibration solution.
Key Product Differences
Variants within the PHA-Series are distinguished primarily by their target pH value and container volume. The part number structure indicates these differences:
- The numeric suffix (4, 7, or 10) identifies the specific pH calibration point.
- The -GAL suffix denotes a gallon-sized package compared to standard bottle sizes.
- The prefix PHAB- distinguishes a separate product line within the series offering similar DI and pH solutions.

Great Product DOESN'T COME IN BOTTLES
Ph solution worked as advertised but was disappointed that the solution came in UN-resealable bags. I was under the impression they were in bottles.

If buffers are susceptible to contamination, how long are they good for after opening the container?
pH buffer solutions have 1 year shelf life. You should follow the expiration date on the bottle.

Does the Standard Certificate Type provide a NIST traceable certificate or do I have to select the CAL Certification?
Yes

How should this solution be disposed of?
Thank you for your inquiry. Standard buffer solutions are comprised of salts and can be drained into a sink and flushed with copious amount water afterwards.
