Single use pH calibration buffer sachets.
These buffer solutions are produced using high purity salts, deionised water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers. Reported values are accurate to +/- 0.01 pH @ 25°C and are traceable to NIST Standard Reference Materials (SRMs).
Convenience of individual packaging:
- Ideal for users that do not calibrate frequently
- Ideal for field use due to portability
- Every sachet is as fresh as the day it was packaged
- Light block packaging prevents oxidation from UV light that could alter the buffer value
Each sachet is marked with lot number and expiration date. Hanna buffers are specially formulated to have an expiration of 5 years from manufacture for an unopened sachet.
Colour coded label for easy pH buffer value identification.
