Measure general pH samples as well as viscous or colloidal samples with the free-flowing sleeve junction design of the Thermo Scientific Orion 8172BNWP ROSS Sure-Flow pH Electrode

This general-purpose pH electrode offers superior performance for dirty, difficult samples such as soils, sludges, colloids, viscous materials, and organics. The junction cleans easily between measurements; pressing down on the cap allows the filling solution to flow through the junction and carries away any contamination that may interfere with the measurement.
