Thermo Fisher, 01X218977, accuCap™ Capillary Junction pH Combination Electrodes - Glass Body, Gel-Filled: Mercury-Free

Unit Size: Each
Better junction
• Single-pore capillary junction is ∽200 times larger than typical ceramic junctions
• Almost impossible to clog, even in difficult samples
• Increased electrolyte flow, greater contact between sample and reference, fast and stable readingsBetter reference design
• Double junction design for enhanced performance
• Diffusion barrier separates silver chloride reservoir from reference electrolyte
• Permits use of silver-free electrolytes, prevents silver chloride loss from temperature-induced variations
• Result: an extremely stable reference potential, providing long electrode lifeMost accurate
• Testing at German Federal Physical Technical Institute in Braunschweig determined this electrode design to be the most accurate laboratory electrode
• SeeTraceability of pH measurementby Petra Spitzer; ISBN 3-89429-877-4 or SSN 0947-7063
• Standard glass body and pH membrane
• Solid polymer-gel electrolyte offers the advantages of the accuCap system in a maintenance-free version
• Provides a more stable matrix than other gelled electrode reference systems
• Gives reliable results in very dirty, ion-weak or protein samples
• Reliable even at low pH or in presence of organic solvents
