Measure biological media, pharmaceuticals, foods and more with Thermo Scientific™ Orion™ ROSS Ultra™ Refillable pH/ATC Triode™ Combination Electrodes. They are ideal for any application where the use of metallic reference electrodes would contaminate the samples. ROSS Ultra electrodes offer the best temperature performance in repeated, varying temperatures of all other electrodes. They have great stability and drift and come with a two-year replacement warranty.

Maintain sample integrity, even in TRIS buffers; ROSS double junction design electrodes contain no silver, which can bind with biological samples. With built-in temperature sensors, these electrodes offer a convenient solution for your routine sample measurements.
