Thermo Scientific Orion 8611BNWP ROSS Combination Sodium Ion Selective Electrode (ISE) with Waterproof BNC Connector, Saturated to 0.02 ppm Measurement Range

The Thermo Scientific Orion ROSS 8611BNWP refillable combination sodium ion selective electrode (ISE) has a glass bulb sensor for measuring the sodium (Na+) concentration in steam condensates, clinical analysis samples, serums, food, wine, glass, sea water, and other aqueous solutions. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. It has a double-junction ROSS reference to protect against silver wire contamination and help prevent clogging in dirty water and solutions with heavy metals or organics. The ROSS reference provides readings that are more prompt, stable, and accurate than conventional sodium ISEs. The electrode has a glass body for an improved seal and resistance to corrosive materials, organic compounds, and solvents, and its glass bulb sensor is formulated specifically for sodium ion measurement.

The ISE has a measurement range that is saturated to 0.02 parts per million (ppm) (saturated to 1E-6 M), and the main interfering ions are K+, Li+, Rb+, NH4+, Ag+, and Tl+. The electrode operates in temperatures ranging from 0 to 100 degrees C (32 to 212 degrees F) and is recommended for use in solutions with pH ranging from 6 to 12. It is 12mm in diameter and 120mm long, and has a 1m cable with a waterproof Bayonet Neill-Concelman (BNC) connector for attaching to meters with a BNC connection. The electrode comes with a 50 mL bottle of ROSS sodium electrode filling solution and one 475mL bottle each of sodium ionic strength adjustor (ISA), sodium known addition standard, 1,000 ppm sodium standard with ISA, 1,000 ppm sodium standard sodium reconditioning solution, and sodium electrode storage solution. The filling solution composition can be adjusted to suit the sample requirements. ISEs respond selectively to ions in the presence of other ions, and they are commonly used for water testing and analyzing biological sam
