pH Buffers

 

Calibration pH buffers are available in a variety of color-coded or colorless pH buffer solutions, in different packaging types and sizes from 15 mL up to 20L. pH buffers are also available in convenient single-use pouches (singlet) and unit-dose powder pillows for on-site and field analyses ensuring freshness, eliminating the possibility of contamination..

Each Hach® pH buffer is NIST traceable for optimum pH electrode calibration with an accuracy of ±0.02 pH at 25° C.

For critical applications and metrology needs, Hach offers Certified Conductivity Standard Solutions with a Certificate of Conformity and Traceability from our Accredited Laboratory. The certificate reports the exact pH buffer value with related expanded uncertainty (k=2). pH Buffers solutions are traceable to IUPAC/NIST pH scale. They offer a unique extended shelf-life period due to a premium aluminum packaging.
