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.

  • Orion pH buffers in 475mL bottles are ideal for everyday use and laboratory and bench pH analysis.
  • Orion pH buffers in 60 mL bottle 5 packs are designed for occasional use and portable and field pH analysis.
  • 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 5 buffer is orange, pH 7 buffer is yellow and pH 10 buffer is blue.
