CPY20 pH buffer solutions guarantee the reliability, accuracy and traceability of your pH measurements.

Temperature curves of CPY20 pH buffers are pre-programmed in all Liquiline series transmitters to simplify sensor calibration and adjustment, reducing your maintenance effort.

The high accuracy and reproducibility of the buffers help you optimize the pH value in your process and to maximize the yield and quality of your product.

CPY20 pH buffers are traceable to standard reference material of NIST (USA) and PTB (Germany), and fulfil the stringent documentation requirements of Life Sciences.

The easily accessible, identical certificates of the buffers simplify your audit trails and improve the reliability of your SOPs.

All used preservatives are FDA-listed for highest product safety in FDA-supervised processes.

Our pH buffer production has successfully passed the tough accreditation process of the German Accreditation Service (DAkkS) in accordance with the specifications of DIN EN ISO/IEC 17025:2005.

We are one of the very few pH buffer manufacturers in the world whose production is completely certified. Additionally, we regularly participate with success in international round-robin tests.

CPY20 buffers are available in seven different values from pH 2 to pH 12.
Field of application
The high-quality CPY20 buffers guarantee pH calibration to ultimate precision. They are produced and bottled in the permanent calibration laboratory that has successfully passed the tough DAkkS accreditation (German accreditation authority). The buffers are specified with an accuracy rating of +/-0.02 pH. They are traceable to NIST and PTB standard reference material and contain only FDA-listed preservatives. Using CPY20 you will achieve correct values that you can rely on.
CPY20 pH buffer solutions are used for calibration and adjustment of pH electrodes in all industries. They are optimized for all routine and high precision sensor adjustments in the process as well as in the lab.
The calibration and adjustment can be conducted with:
Memobase Plus CYZ71D software
All transmitters of the Liquiline series
All conventional pH transmitters on the market
