ScienceLine Plus - Precision in every application
In very demanding cases, off-the-shelf pH electrodes are just not quite good enough for certain samples or measurement conditions. These instances include (but are not limited to) measuring the pH of highly alkaline samples, samples containing sulphides or proteins and, for practical purposes, measuring the pH of a small sample quantity when in a small or deep vessel such as an NMR tube.
Our ScienceLine Plus range of pH electrodes meets the needs of these challenging conditions.
- pH electrode with sphere shaped membrane
- Platinum diaphragm
- A-Glass // H-Glass
- Silamid® reference system with silver ion barrier and double-electrolyte for faster, more stable results and a longer electrode lifespan
What makes ScienceLine Plus better than ordinary pH electrodes?
Unlike many pH electrodes that use chlorinated silver wire to form a silver/silver chlorine reference system (diaphragm) that degrades over time when in contact with certain sample types, all ScienceLine Plus series electrodes employ a Silamid® double reference with silver-ion trap that facilitates universal use, even in protein or sulphide containing samples. The diaphragm itself is a maintenance free encapsulated gel system, and the silver coating of the inner tube has significantly larger (5x) silver surface compared to the silver wire system making for a faster, more stable and longer. The outer bridge electrolyte consists of the proven 3 mol/l KCl, which may also be replaced by other bridge electrolytes if need be.
