Calibrate the pH range of your Hanna Instruments device!

They seal the solution in airtight containers. They then apply a tamper-proof seal. This process ensures the quality of the solution. Hanna specially formulates their line of technical calibration buffers. Each unopened bottle of solution has an expiration date of 5 years from the date of manufacture.
