Fisherbrand™ accumet™ Polymer Membrane Combination ISEs, Mercury-Free: Potassium

Sensor sealed in epoxy body

• Sensing modules contain liquid internal filling solution in contact with gelled organophilic membrane
• Membrane is impregnated with a selective ion exchanger for ion of interest
• Sensors are sealed into durable epoxy body with built-in reference half-cell
• Permit fast, precise measurements in aqueous solutions over a wide range of concentrations
• Epoxy body provides chemical resistance

• Tough, chemical-resistant epoxy body
• Membrane assembly sealed to body
• Continuous electrical shielding and insulation of internal elements, cable and connectors
• Extremely stable, reproducible readings with a minimum of electrical noise
• Lower detection limits than conventional ISEs
• Rapid response time that lowers cost per test
• Individually tested, serialized to meet GLP requirements and backed by the Fisher Scientific Technical Applications staff

• Diameter: body, 0.5 in. (12.7mm); cap, 0.625 in. (16mm)
• Length: body, 4 in. (10.2cm); cap, 1 in. (2.5cm); overall, 5 in. (12.7cm) 

Potassium Electrode

• Aids in analysis of serum, urine, saliva, other bodily fluids
• Used in testing soils, sewage, fertilizers, foods and beverages
• Filling solution is 5M NaCl
