Orion 920707 NITRATE 1000PPM AS N STANDARD 475ML

Take accurate, reproducible ion concentration measurements by calibrating your Ion Selective Electrode with high-quality Thermo Scientific™ Orion™ ISE Calibration Standards. Use these standards with electrodes including ammonia, chloride, fluoride, nitrate, potassium, silver, sodium and sulfide. Orion calibration standards are NIST traceable and manufactured under ISO 9001 quality standards.

Use the Orion ISE calibration standards with our extensive line of ion selective electrodes (ISEs) for ammonia, ammonium, bromide, cadmium, calcium, carbon dioxide, chloride, chlorine, copper, cyanide, fluoride, iodide, lead, nitrate, potassium, silver, sodium and sulfide analysis. 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.
