Description:
Thermo Scientific Orion 8135BN Epoxy Body ROSS Flat Surface Combination pH Electrode with BNC Connector measures pH of soft, moist surfaces—both solid and semi-solid—such as agar gel plates, meats, bread dough and similar samples. It works in extreme cases of samples varying from one another by 50°C or more with drift less than 0.002 pH per day and minimized restandardization. Operating range is 0 to 100° C. Results are three to five times more precise than those obtained with conventional electrodes. Glass Fiber Junction is standard. Conventional electrodes can leach metal ions into the filling solution and subsequently into the sample. ROSS™ Electrodes do not contain silver or mercury to react with the sample or clog the ceramic frit. Use ROSS™ pH Electrodes where trace amounts of metal ions, in such samples as biological media, foodstuffs, and pharmaceuticals, cannot be tolerated.
