HI6000 Series Millesimal pH Buffer Solutions – pH 4.010, pH 7.010, & pH 10.010


The accuracy you need.

Millesimal buffer solutions are designed for customers who require a resolution of 0.001 to meet the increasing need for assured accuracy in pH measurements.

Certified for quality results.

Our buffer solutions are prepared according to precise formulas and are standardized with a pH meter and electrode calibrated with NIST standards. A Certificate of Analysis (COA) is available as needed for ultimate traceabiltiy.

Marked with lot number and expiration date for Good Laboratory Practice.

Hanna pH buffers are specially formulated to have an expiration of 5 years from manufacture for an unopened bottle.


Electrode Storage Solution (500 mL) – HI70300L


Condition for longer pH electrode life.

To minimize junction clogging and to ensure fast response time, it is important to always keep your glass bulb and pH junction hydrated. If a probe is dry, the junction may become clogged causing the pH readings to be erratic.

Proper storage of your electrode will ensure reliable measurements and a long electrode life. Our storage solution is specially formulated to keep the pH glass hydrated while minimizing organic growth.


General Purpose Cleaning Solution (500 mL) – HI7061L


Specially formulated for cleaning pH electrodes.

Electrodes can become dirty from use and will produce inaccurate results. Our general purpose cleaning solution eliminates impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly.

Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. Simply immerse your pH electrode in the HI7061L cleaning solution for 15 to 20 minutes to dissolve any mineral deposits or other coatings for fresh electrode.
