Quality buffers for calibration and adjustment of pH electrodes with buffer analysis certificate The quality buffers CPY20 are traceable to reference material of PTB and to standard reference material of NIST and cover the full pH measurement range. the buffer solutions are obtainable with the following pH values: 2.00, 4.00, 7.00, 9.00, 10.00 and 12.00. The buffer analysis certificate contains, besides the product description, detailed information about the exact measured pH value, date of production and shelf life, as well as the lot numbers and nominal pH values of the used standards. Additionally a detailed description of the traceability procedure is given. Thus, the certificate fulfills the demanding customer requirements e.g. of the pharmaceutical industry. The new quality buffers are produced and bottled under highly hygienic conditions in a specially developed mixing and bottling plant.
