Thermo Scientific Orion 8103SC Glass Body ROSS Semi Micro Combination pH Electrode with Screw Cap Connector fits test tubes, measures samples as small as 0.2mL. 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. Ceramic 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. NOTE: Electrodes with a screw-cap connection (-SC) ship without connecting cable.
