Fisherbrand™ accuCap™ Capillary Junction pH Combination Electrodes - Glass Body, Gel-Filled: Mercury-Free
Large junction for increased flow, minimal clogging
Brand: Fisherbrand™
Additional Details : Weight : 1.00000kg
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
- 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
- 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
