---|---|---|
* provided Cell Culture Flasks are used without further handling in physiological solution ** at 100 rpm & in cell culture media | ||
Measurement range | 0 - 100 % O2 | 5.5 - 8.0 pH |
Resolution | ± 0.01 % O2 at 0.21 % O2 | ± 0.01 pH at pH = 7** |
Accuracy | ± 0.4 % O2 at 20.9 % O2 | ± 0.1 pH at pH = 7 with one-point adjustment ± 0.2 pH at pH = 7 with pre-calibration |
Drift | < 0.01 % O2 per day (sampling interval of 1 min.) | < 0.01 pH per day (sampling interval of 1 min.) |
Measurement temperature range | from + 5 to + 50 °C | |
Response time (t90)** | at 25 °C: < 60 sec. | |
Properties | ||
Compatibility | Aqueous solutions, ethanol (max. 10 % v/v), methanol (max. 10 % v/v), pH 2 - 10 | |
Cross-sensitivity | Typically no cross-sensitivity in culture media | Reduced to ionic strength (salinity); a high concentration of small fluorescent molecules in the visible range can interfere |
Calibration | Sensor flasks are delivered irradiated. Pre-calibrated |
