PH Buffers

pH buffers

Hach calibration buffers are available in a variety of color-coded and colorless solutions – from bulk 20 L containers down to single-use 15 mL vials.

They’re also available in convenient Singlet form and unit-dose powder pillows for on-site analysis. Both Singlets and powder pillows assure freshness and eliminate the possibility of contamination. All buffers are NIST traceable and accurate to ±0.02 pH at 25°C.

For critical applications, Radiometer brand pH buffers accurate to ±0.010 pH at 25°C are available. Each buffer is delivered in an airtight can and is supplied with a Certificate of Conformity and Traceability.
