Read viscous liquid samples quickly and accurately without the sample coming into contact with silver ions with Thermo Scientific™ Orion™ AquaPro™ pH Combination Electrodes, which 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.

Feature improved electrode life, low maintenance, fast response time and clean junctions. Patented reference system and double-junction design prevent silver ions from contacting sample.
