High quality buffer solutions ensure accurate pH measurements time after time.

• Colour coded
• Potassium hydrogen phthalate based pH 4 buffer (red)
• Phosphate based pH 7 buffer (yellow)
• Borate based pH 10 buffer (blue)

Ready-to-use pH buffers are manufactured in large lots to stringent specifications and utilize quality control procedures to reduce lot-to-lot variability. You can eliminate the time and expense of preparation and standardization of solutions, helping streamline high-volume analytical work in applications such as quality control.

Solutions are available in both clear and color-coded varieties.

A certificate is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.
