Laboratory ORP Buffers
Quality ORP Buffer Solutions for Verification Purposes
An ORP (Oxidation-Reduction Potential) buffer is a standard solution used for the verification of all common ORP/redox sensors. Over time and use, sensors are affected by their environment, so verification with a lab ORP buffer helps ensure precision and extend a sensor’s reliable operating life. METTLER TOLEDO ORP buffers are GHS compliant, and the small-volume packaging minimizes contamination risk while guaranteeing a fresh solution for every verification measurement.
Advantages of METTLER TOLEDO's pH Electrolytes and Maintenance Solutions
Verify the Sensor
The results obtained with a laboratory or field ORP sensor are only as accurate as the standards used for verification. METTLER TOLEDO offers quality standards in small bottles that help to eliminate contamination risk, ensure reliable ORP/redox readings, and validate the measurement results.

FAQs
What is an ORP buffer used for?
ORP buffer solutions are used for the verification of all common redox sensors. They are not used for calibration purposes. Similar to other solutions, an ORP buffer is temperature-dependent. It is therefore important to know the measurement temperature of the ORP buffer. A table on every bottle label indicates redox values at different temperatures.
Where can I obtain a certificate for my ORP buffer?
All METTLER TOLEDO ORP buffer solutions are available in handy bottles with no-fuss labels. If larger quantities are required, then our 6-packs are the right choice. To guarantee maximum traceability, a global test certificate exists for all redox buffers. Furthermore, compliance with regulations is critical for us. All SDS (Safety Data Sheet) and labels contain information according to GHS (Globally Harmonized System) in local languages.
