Simultaneous Oxygen and pH Monitoring in Multidishes
These 6-well multidishes have an oxygen and pH sensor integrated at the bottom of each well. They are delivered irradiated and pre-calibrated and are therefore ready-to-use. These SensorDishes® are read out with the SDR, which shows either the measured oxygen or pH values online, while the other parameter values are stored and can be analysed after data export.
- Manual calibration possible
- Ideal for cell cultivation & tissue engineering

Disposables are delivered beta-irradiated
Can I re-use the SensorDishes®? Can I use the SDR with other formats than the 24-well plates? Do cells grow on the sensor inside the SensorDishes®? Do SensorDishes® come sterile? How do I import data into excel from a text file containing measurement data? How long can I use a SensorDish®? How long do I need to equilibrate before starting a SDR measurement? I use the OxoHydroDish (OHD6) with the SDR. How do I see the values of both parameters (oxygen and pH) with the SDR software? The SDR software shows "no sensor" instead of a value. What is the reason? What is the time of delivery? Which substances can interfere with the optical O2, pH and CO2 measurements? Which toxicity tests where done with the SensorDish®? Why are there two different calibration data sets for SensorDishes®? Why do I need to equilibrate my samples for such long time periods before measurement with the SDR? Why do I see peaks in the graphs of the SDR software (especially in the oxygen signal) when I open the incubator door / take the plates out of the incubator? Why does the SDR software show pH<5, although I know that my sample is basic?
