Simultaneous Oxygen and pH Monitoring in Multidishes
OxoHydroDish OHD6
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.
- Ready-to-use
- Pre-calibrated
- Manual calibration possible
- Ideal for cell cultivation & tissue engineering
