Combination ORP probe

WhatsApp Order

A Combination ORP Probe is an integrated electrochemistry sensor that combines both the platinum sensing electrode and Ag/AgCl reference electrode into a single probe body, designed for precise measurement of oxidation-reduction potential (ORP) in clinical diagnostic, blood bank, and research laboratory applications . ORP (also known as redox potential) measures the total oxidizing or reducing capability of a biological solution, providing information about the oxidative stress status and electrochemical balance of patient specimens .

The probe features a platinum band sensing element (for ORP measurement) and an Ag/AgCl reference system, with body materials available in epoxy for rugged general-purpose use, glass for chemical resistance in organic solvents, or PPS (polyphenylene sulfide) for super rugged industrial applications . The reference junction options include porous Teflon for general use, Sure-Flow for clogging prevention in dirty or viscous samples, and glass fiber or ceramic for high precision, with single-junction or double-junction designs . Select models (e.g., Triode series) integrate a built-in temperature sensor for automatic temperature compensation (ATC) . Response time is rapid, with stable readings achieved within 10-30 seconds .

For the clinical laboratory scientist and medical technologist, the combination ORP probe simplifies redox measurement of biological fluids including serum, plasma, urine, and blood products—eliminating the need for separate reference and sensing electrodes while reducing sample handling . For the clinical pathologist and researcher, ORP measurement of patient specimens may support the diagnosis, evaluation, and monitoring of conditions including trauma, viral infection, and suspected myocardial infarction, as well as assessment of oxidative stress and systemic inflammation . For the blood bank technologist, ORP measurement of stored blood components can help evaluate quality and storage-related oxidative changes .

Gel-filled (sealed) models require virtually no maintenance as there is no need to refill the reference chamber, while refillable models allow for extended service life . The probe’s rugged epoxy body and Sure-Flow junction design is well-suited for dirty or viscous biological samples . Compatible with ORP meters accepting BNC connection, the combination ORP probe is an essential tool for clinical chemistry laboratories, blood banks, transfusion medicine services, and research facilities requiring accurate, reproducible ORP measurement for patient sample testing, quality control, and diagnostic applications .
