Fisherbrand™ accuCap™ Capillary Junction pH Combination Electrodes - Glass Body, Gel-Filled: Mercury-Free

Description

• 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 readings Better 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 life Most accurate Testing at German Federal Physical Technical Institute in Braunschweig determined this electrode design to be the most accurate laboratory electrode See Traceability of pH measurement by 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
