Non-invasive pH Measurements in 6-Well Dishes
HydroDish® HD6
Pre-calibrated pH sensors are integrated at the bottom of each round well of this 6-well multidish and are read out with the SDR SensorDish® Reader non-invasively. The HD6 are delivered beta-irradiated and can be put inside an incubator.
- Ready-to-use
- Pre-calibrated
- Manual calibration possible
- Ideal for cell cultivation & tissue engineering
