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
