Thermo Scientific Orion ROSS Ultra pH ACT Triode Combination Electrode

The Thermo Scientific Orion 8302BNUMD ROSS Ultra Triode is a high-performance, refillable pH/ATC combination electrode designed for demanding laboratory environments. It integrates a ROSS reference system and an automatic temperature compensation (ATC) sensor into a single, chemical-resistant glass body, providing rapid and stable readings even in samples with extreme temperature fluctuations.

Core Capabilities & Performance

The ROSS Ultra technology is engineered for high accuracy and long-term stability without the drift common in standard silver/silver chloride electrodes.

• Integrated Temperature Sensing: Measures both pH and temperature simultaneously through a single probe, simplifying workflows.

• Rapid Stabilization: Provides readings stable to 0.01 pH in less than 30 seconds, even when moving between samples that vary by as much as 50°C.

• Double Junction Design: Protects samples from silver contamination and makes the electrode ideal for use with TRIS buffers, sulfides, and proteins.

• Extreme Precision: Offers an accuracy of 0.03 pH (when using ATC) and a precision of 0.01 pH, with a drift of less than 0.002 pH per day.
