Fisherbrand™ accuCap™ Capillary Junction pH Combination Electrodes - Glass Body, Gel-Filled Spear Tip - Mercury-Free
Large junction for increased flow, minimal clogging
Supplier: Fisherbrand™ 3590133
Description
Large junction for increased flow, minimal clogging
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
- Glass body and pH membrane
- Rugged spear tip is ideal for soft foods
- Polymer gel electrolyte provides reliable performance with difficult samples
