Descripción

General description

The accuracy of pH measurement results is directly affected by the buffer reference materials used in calibration. We have a distinguished range of buffer solutions and substances for the exact calibration of your pH measurement equipment. Using Certipur^® reference materials, you benefit from maximum accuracy, reliability and convenience and avoid costly repeat analyses.

Our wide range of pH calibration buffers offers ideal products and packaging for your individual need. All buffer solutions are traceable to NIST (National Institute of Standards and Technology, USA) and PTB (Physical Technical Institute, Germany) primary reference materials. Buffers solutions are offered in 1L PE bottle, measured at 20 °C or 25 °C.
