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
