The Thermo Scientific® Orion ROSS Ultra™ line of electrodes has twice the warranty and greater stability than its predecessor. It uses a unique reference system developed by Thermo Electron that offers longer life, greater stability, and fast results, regardless of sample composition or temperature. Unparalleled pH response to temperature changes. These refillable electrodes have a two-year replacement warranty.

Thermo Scientific Orion ROSS Combination pH Electrodes provide readings stable to 0.01 pH in less than 30 seconds, even in the extreme case of samples varying from one another by 50°C or more. Operating range is 0 to 100° C. Results are three to five times more precise than those obtained with conventional electrodes. And, because drift is less than 0.002 pH per day, restandardization is minimized. Ceramic junction is standard. Conventional electrodes can leach metal ions into the filling solution and subsequently into the sample.

Thermo Scientific® Orion Sure-Flow® is a unique, free-flowing liquid-to-liquid junction that assures you the most stable, drift-free measurements. The easy-to-clean junction never clogs, simply press the cap and flush the junction area. Dirty or viscous samples can be easily measured without a clogged junction. Waterproof connector is standard.

Thermo Scientific® Orion™ Micro Combination pH Electrodes measure samples as small as 0.5 µL and are available in a variety of sizes, including a needle tip to pierce septa and a long-bodied electrode for NMR cells. With Ag/AgCl references, Micro-pH electrodes provide fast, stable responses with a minimum of sample.

Thermo Orion AquaPro™ pH Combination Electrodes read viscous liquid samples quickly and accurately without the sample coming into contact with silver ions. They have a clog-resistant and open double junction reference system. These electrodes are ideal for measurements in samples containing proteins or TRIS buffers and that do not contain mercury. The electrodes require minimal maintenance because there is no fill solution; instead they have a polymer gel reference.
