Work with ease using this color-coded pH buffer kit that includes three buffers, storage solution and a storage bottle.

• Orion pH buffers are NIST traceable and manufactured under ISO 9001 quality standards.

  Orion pH buffers are color-coded for easy identification: pH 4 buffer is pink, pH 7 buffer is yellow and pH 10 buffer is blue.

Thermo Scientific™ Orion™ All-in-One™ pH buffer kits include pH 4.01, 7.00 and 10.01 buffers that are color-coded for easy identification as well as storage solution to help ensure your pH electrode is properly maintained. Using high-quality pH buffers to calibrate your pH electrode and pH meter is the best way to ensure your pH measurements are accurate and reproducible. Orion pH buffers are NIST traceable and manufactured under ISO 9001 quality standards.

Whether you are in the lab or in the field, you can be confident that Orion solutions will deliver accurate and repeatable measurements. Orion solutions are produced in controlled batches using ultrapure water and undergo rigorous quality testing throughout the process to prevent contamination. Our strict quality procedures verify correct bottle labeling and volume, so each batch meets specific lot release criteria. Bottles are sealed and torque-tested to ensure bottle caps are secure and solutions remain free of contamination. Rigorous lifetime testing ensures sealed Orion solutions remain within published specifications for their entire shelf life and do not degrade over time.
