Combination pH Electrodes, Flat Surface

The unique Thermo Scientific® Orion Sure-Flow® Junction is a free-flowing liquid-to-liquid junction assures you of the most stable, drift-free measurements. The easy-to-clean junctions never clog-simply press the cap and flush the junction area. Release the cap and the junction is reset. Now even the most problematic, dirty or viscous samples can be easily measured without...

The most common cause of error in pH measurements is temperature. The slope of a pH electrode is highly dependent on temperature and pH buffer values and sample values change with temperature. For the most accurate results an ATC probe is always recommended. The epoxy body Thermo Scientific® Orion™ ATC probes (PH4341-1/-3) are not recommended for use in organic solvents,...
