This line of buffers with millesimal accuracy (±0.002 pH), HI 60xx, has been prepared to meet the increasing need for assured accuracy in pH measurements. Each bottle of the series HI 60xx is provided with a certificate of analysis, prepared by comparison with NIST standards.
The colors on the HI 60xx series packaging correspond to a given standard pH value. They make it easy and safe to identify the buffers to be used.
